I think what he's effectively looking for is a kind of soundboard application. And I've actually been thinking that *I* would love that for on-the-go podcast hosting where I'd like to be able to queue up sound files ahead of time to play during the show (ie: to play news bite sound clips, sound effects, etc.). These other appd like PyAno and PyDrum aren't very good soundboards--they appear to be intended as instruments.

Also.. HUGE thanks to fuutott for that app.. I haven't tried it yet but it sounds like the right idea!
