I fancy a bash at Tachyon to see if OSS is capable of utilising that many cores....
From what I have seen over the years OSS is often first to get the new/latest code tricks, but, I am biased because most of the OSS stuff I have used or played with the people have bent over backwards to help me, often much more so than places that were being paid thru the nose to do the same.
So now I always try to go OSS, but you need to give them a good amount of feedback first (not saying you will not) but IMO it is that which has helped me more at later dates. You stick in their minds and they might have taken an interest in what you are doing before you ever need them.
With the service co's you are just another in a long list for that day and they are there because they have to be and you are just another number to get thru.
The only ray tracing SW I know of is POVray and only because I and some of the coders have met in the same places and had things in common.
