I've diddled with this a bit, but when you have multiple simultaneous
collisions (imagine a pool game where the que ball hits two targets
at the same time) there ends up being quite a bit more sound than
expected.  I'm exploring the joint feedback option, though I may
revisit the idea of simply examining velocity vectors and trying to
make sense of simultenaity (sp?) later...

	thanks, all!
