Well, I have been trying to think of a way to reduce the "grainyness" 
problem without requiring too many samples...maybe by initially doing 2 
groups of samples, measuring the difference between their results, and 
optionally making additional samples if they are too different...or 
something like that.
What would be nice would be the ability to reuse samples, which would 
not only be smoother, but a lot faster...but to do that well would 
require a "pre-trace" stage, similar to radiosity, and would consume a 
lot of memory. And I have no idea how to do it...
