I'm always impressed how people can demand support for there purpose. I
have the feeling some forget that blender is an opensource project. If I
think it should
go in my prefered direction, than I would sit down and write a patch for it.
TY for bringing us cycles and all the new features for free. If it is
important then I would
think I would be able to go to the store and buy myself a cuda based
card for under
100 EUR or start programing.
My 2 cents.
