Thanks for the response Bryster.  That confirms what I was thinking.

I like 5.5 for some reason its my favourite version of Bryce.

In regards to the Bryce Lightning thing, I'm going to go ahead with the 64-Bit install of Windows 7 on the main machine.

I have upgraded my previous Pentium III systems to Pentium 4 systems for the render farm.

Since I'm weak when it comes to Bryce and my strength is more with getting machines running and such.  I'd like to revisit the idea of donating CPU Time for those who need to have a big render done.
