What exactly do you require the programmer to do?
I might be interested & have a few weeks off now
I have msvc6sp3 & the msdn lib
but I am not extremely skilled ;-/
& only have a single cpu
The msdn lib will help me when it comes to thread functions etc.

A small percentage of NT users who are fortunate enough to find
software that supports it.

Too bad that Windows9x doesn't support multiple processors. NT supports,
but I think that the number of NT users are an extremely small percent of
the Windows9x users.
  So I think it would be a waste of time.

yes but there is win2000, and in a few years i would suspect that even home
versions of windows will have multi cpu support, while threading may be a
good idea, at the moment it seems like a lot of work with benift for the
few.. mind you once its done, its done so to speak and it is something the
pov team are going to have to look at over the next few years.

not being a C programmer myself i am not sure, neither am i exactly sure
what state the completed sections of win32 pvmpov are at.

i don't think the povray source code is a good place to learn, i had a look
a while back when i was learning C and decided after 10 mins that there was
not a chance i was going to mess !!

> & only have a single cpu

there is no way you could develop with only one cpu / one machine, you would
be coding blind.

> The msdn lib will help me when it comes to thread functions etc.

sure mdsn is a great help, but you have to remeber - its finding the help in
there which is often half the problem! - the amont of times i have spent
several hours trawling the cd's when all i needed was a simple 'do it this
way' !!!

  Win2000 is more WinNT than Win9x. It's made more for the same uses as NT
is rather than for games and such. I think that many win9x games don't even
work in Win2000.

  Of course Linux (and other free unix systems) support multiple processors
and still there is no multithreaded povray for them.
  PVM-pov exists no more, and even when it existed it didn't work with
radiosity.
  Multithreading has also many other problems. It's more problematic than
it may sound. I wrote an entry in the VFAQ about this.

  Another thing is that since it's not made by the povteam, this version will
always be one step behind the official version.

I think I have noticed an improvement to all my 3d applications like Povray,
MegaPov, and the swarm off modeling tools I've been using. W2k is very
stable, me likey very much.

I think photons wouldn't work either :-(

For POV-Ray 3.5 we will at least have a list of all the global variables and
in which function(s) they are used.  It is surprising, there are even
globals that are used to just pass an argument from one function to another.
While about 80% of the global variables in POV-Ray could be removed in short
period of time, at least 20% would be next to impossible remove.
That is one of the reasons why there will be some kind of rewrite for
POV-Ray 4.0.

One of the long planned goals surely is to offer multithreading and network
rendering, but this will surely not happen before POV-Ray 4.0 :-(

  Still it requires a lot more resources than should be reasonable.
  It seems that microsoft thinks "the higher the stability, the more memory
and other resources needs to be used" when it's more or less the other way
around. IIRC the recommended amount of memory for Win2k is 128MB while the
recommended amount of memory for Linux is something like 16MB.

isn't windows ME supposed to be the gamers' solution to an upgrade? 
it's not win2000 right?  anyone know when winME comes out?
