Actually, just curious here... would it help in any way with speeding up 
shadow calculations? If you have a large hard-to-bound-well object with 
dozens of lights, is there anything you could do in parallel (such as on a 
GPU) that might be able to tell you which lights are known not to be visible 
at a particular 3D point?

That would seem an easier problem to apply GPU to than the full 
ray-intersection and texture and color and such, because you could fall back 
to a CPU-based test in the event you came back with "I don't know"?

   Forget "focus follows mouse." When do
   I get "focus follows gaze"?
