Perhaps you are confused by this [openbsd.org].
Why would you purchase a set of discs to perform multiple installs when OpenBSD developers recommend against using a static copy?
They don't. OpenBSD releases come at regular 6 months intervals (3.2 was a month early). That's what you should be using. You can use the snapshots or even the current CVS if you feel brave.
Sure, I can understand buying copies to support OpenBSD. I buy Redhat for the same reason, it's more principle than the actual material in the box.
You are correct. There's a slight difference, though, OpenBSD is not trying to turn a profit, just cover the development costs.

The reason it has changed, is merely that they don't update it a precise intervals. They essentially stopped the clock last time they updated (I believe because of some claimed exploit near the 6 year mark that never worked out), and finally brought it up to date recently.

If Theo would deny this work, it would probably be on those grounds. It was indeed one of the reasons he mentioned to me.
The most likely place for race conditions to occur on SMP systems is with threading. I have yet to see a totally solid threading implementation that is totally devoid of race conditions of any kind wrt locking/freeing/semaphores/etc. Usually kernel developers solve most of the problems by passing one big lock around (like linux does, and FreeBSD (ever heard of Giant?))
All in all good news that these guys are working on it indeed. My main concern is seeing this project die because it has the chance of being shot down by Theo.

The conventional wisdom that an operating system should be judged according to it's bells and whistles is what's wrong with the software industry. An OS should be judged by two things: Does it do the job I require of it, and does it do it well?
There are many many jobs that do not require SMP. There are many many jobs being done on SMP boxes that do not require SMP. As the price of processors has diminished, SMP is just a cool thing to buy. I'd be willing to put money down saying that 75% of the SMP boxes out there aren't needed (if that was measurable).
So, if you want to judge your OS based on features you don't need, then go for it. I use OpenBSD because it is the best choice for that particular need. If you want to assume that one OS is the Uber-OS because of the back panel of the box, then go for it. I'll assume a particular OS is best for the task at hand, and go with that.
I'm not part of the OpenBSD project (nor do I play one on TV), but one of the central points behind it is that they don't put in things unless they are needed. So far it doesn't seem like SMP has been justified in the great scheme of things (no surprise given the actual need in the wild).

Now, SMP is not necessarily something people "start needing"; you don't usually realize one day that "gee, now I really need SMP". For many things it isn't strictly required, like you say -- after all, most systems only scale up decently to 4- or perhaps 8-way systems, and common rule of thum is that you get about sqrt(num_procs) output (assuming you get enough CPU load for all processors)... and so you can same amount of work done by getting twice as fast CPU (instead of 4-way SMP system).
However, having SMP capability as an option is a Good Thing. For servers it allows nice high-end scalability (esp. with Sun boxes, E10K and co. wouldn't rock if it wasn't their SMP-scalability coupled with kickass I/O.. but those beast scale well past 8 CPUs). For desktop systems it allows for better interactivity (especially on traditional unix[ish] system that have batch-job oriented scheduling), smoother UI.

I have much less experience with the BSDs than I do with the various GNU/Linux distros, so I hope someone will answer my question rather than flame in response. I've long been an advocate of reducing the number of different and nearly equal (in functionality) ways to do the same thing, regarding what I would call redundant software projects. In my view, the necessity of competition in a market for physical goods (the need to keep costs down and quality up by preventing monopolies) does not exist with OSS. If a company producing OSS decides to raise prices or slow development or include unpopular features, anyone else is free to keep using older versions at the very least or fork the project and continue development with positive goals at best. With the necessity for competition removed, a market containing multiple, redundant, competing (for mind share) OSS projects is inferior to a market containing a single, popular OSS project that satisfies a specific need. Incompatibilites crop up. The support base is divided. Developer time is divided. Skills must be learned twice. I would greatly prefer a single desktop environment (and widget set and cut 'n' paste mechanism) over the current situation. In Erpo's-the-emperor land, there is only one gnu/linux distro.
Remember, these are just my opinions.
My question is this: while there are a number of idealogical, license-, or ego-related reasons why maintainers of gnu/linux distros (or desktop environments, or whatever) would resist a merging of sofware or elimination of obviously inferior options (obviously inferior in the "there's 1001 gnutella clients and 99% of them suck" sense), is there the same kind of resistance in the BSD community to merging all three main flavors?

I've built a library of almost all the essential references for Unix, including a complete 'real' manual set from 4.3BSD (it's great to use the tutorials from the old days- I'm starting to appreciate 'ed' as a real editor after reading Kernighan's tutorials), the 'devil' BSD book (McKusick/Bostic/Karels/Quarterman), 'The Basic Kernel' 386BSD book (Jolitz and Jolitz), Bach and (of course) Tannenbaum.

I see Linux as generally growing away from it's UNIX roots, part of why as I came to like UNIX more and more I liked Linux less and less and gravitated to one of the BSDs.
The BSD forks were probably a good thing, as it's allowed the BSD systems to thrive and grow in several directions.

I assume you're referring to the stories from several months ago about a proposed deal where UW's Computer and Electrical Engineering department would, as part of a larger research sponsorship deal with MS, agree to make C# the language used in a first year class for CompEng students. There was a huge outcry against this by most CS and CompEng students and profs. Also, note that the School of Computer Science, in the Faculty of Mathematics, had nothing to do with this deal.
It is my impression that there are many UW students who use or contribute to Open Source projects. Profs are more than willing to make an occasional joke in class at Microsoft's expense. And most CS students (I can't speak for CompEngers) don't touch any MS products for programming projects past first year, by far preferring to use the provided unix labs.
Do I think the CompEng department's decision regarding C# bad? Very much so. But as I understand it, this decision was made by a few key people who stretched their authority, when really they should have consulted with more people. In fact, Engineering profs have called UW administration on this decision, leading to a decision that before the MS deal can be finalized, it must be approved by "the Electrical and Computer Engineering Department Program Committee, Faculty of Engineering Admissions Committee, Faculty of Engineering Academic Committee, Faculty of Engineering Undergraduate Studies Committee, Year 1 Implementation Committee, Senate Undergraduate Council, UW Registrar's Office and the senate as required by UW policy and practice." This, in my opinion, effectively has killed the deal. See this article [www.caut.ca] for more about this. [Note that the article implies that the proposed MS C# deal would have affected all first year programming classes. This is untrue: only first year CompEng classes would have been affected; CS students would have been fine.]
The very reason that this decision was such as big deal at UW is that it goes so very much against the prevalent attitude there. And the very large amount of negative feedback they got from UW students and profs in the CompEng and CS departments should ensure that something like this doesn't happen again at UW.

Sun bit the bullet and shifted to SysV for Solaris 2.x, hence the renaming and major version increment (though IIRC SunOS 4.x was never called Solaris 1.x until Solaris 2.x came out - go figure). The Sun marketroids consequently spat on everything BSD based explaining how the way ahead was SysV. Before that, of course, they spat on SysV explaining how superior BSD was. Marketroids, you see. The other big players (AIX, HP-UX, and, I believe, Tru64 or whatever they call it now) are also SysV based. This was no doubt one of the compelling reasons for Sun's switch, at the time. Which brings me to my point - please name come commercial BSD implementations that have "very good" [sic] SMP.
