Absolutely. If it helps to the continued development to a faster Cycles, then yes.
I just went back and read the edited OP. There have been a lot of changes to it.
He is giving it to Blender at the end of the year, and there are constant updates. He now has my serious interest in paying for this development.
Part of the overall problem with this originally was that the OP was a mess. It was very unclear as to what was being offered. Now that it is much clearer to me, I do think I’ll be purchasing this in the near future.
