One solution would be to trace one ray, if it hits an object, check that 
object for a flag that tells whether or not to supersample it, and fire 
additional samples based on that information. This would be done at each 
level. It should work correctly with transparency and media, although it 
should probably be turned off when "global" anti-aliasing is turned on.
