Yeah, I figure it's something that definitely warrants another look, and 
I was just putting out a feeler to see if someone already took that look.

Hopefully I'll have time to look at it this summer.  Module support is 
really important to me; modules are _the_ video game music (dissenting 
opinions aside ;-).  I'm going to be working on additions to glTron for 
my senior project this coming fall and spring, and it'll look good for 
me if the sound works right.

Thanks for the lead.
