No matter whether you distribute gc-shaders or not, part of your userbase will have to make changes to the shader, is what I'm saying. So whatever the shader you distribute is, make sure it's easy to apply or remove GC as necessary. I have poser pro and I know bagginsbill has Poser pro. With the ability to have 6 gigs of ram available to rendering, I could never go back to poser 7.
