Something (nearly) unrelated wich just came to my mind while reading this 
sentence:

Does POV do some kind of depth sorting?
That means, first check for intersections with the object wich bounding 
box is nearest, and if an intersection is found and the intersection 
point is outside the second-nearest bounding box, then don't test for 
intersections with any other objects?
