This is the part that isn't workable. Each pixel depends on the entire 
scene, unless you remove shadows, reflections, refraction, radiosity, 
photon mapping, etc...

Each processor would have to work with the entire scene. And to keep 
things like radiosity consistent over the image, you couldn't just give 
each processor its own copy of the scene data, all the processors would 
have to share it and add to it on the fly.
