Stewer, I agree with you 100%. It might be a couple years before major studios pick up on these new renderers for their pipeline, but eventually it will happen. I don't know about Brazil, but Vray's irradience mapping and photon mapping allow for some VERY fast environmental GI, especially geared towards animation. For example, if it takes several hours to render the first initial frame, it's probably worth it since you only have to run that lighting calculation once for any camera move, and then subsequently you can render thousands of frames in a fraction of the time based on that initial cached solution. Separate passes with matte and shadow composits can be used for moving objects where the light needs to change in every frame. Anyway, they really should open a "Render Theories" forum where we all can discuss the pros and cons of all the renderers out there. Now that would be interesting.
