Hey I've been looking for something like that, too. Let me know when you 
have it done! :-P

Seriously, I believe I've seen similar things in the Windows world, but 
I'm coming up short for Linux solutions.

I know of one German repeater which is streaming to ogg vorbis, but it 
doesn't act on squelch, AFAIK. I believe this could be accomplished with 
a "descriminator tap," but a smart application could be taught to 
recognize when the squelch kicks in.

I'll look around to see what might be Out There(tm).
