Paulo -
   Perhaps an interesting concept would be to write a channel driver 
that turned audio directly into an MP3 stream that could be uploaded 
to a broadcasting server (or served locally).  Then  you could just 
use the streaming methods to play off of localhost, or you could use 
it to transmit up to a larger broadcasting system to distribute to 
other consumers of the media.  It may be possible to do this with an 
EAGI and sox and named pipes, but that's complex and easily lost to 
the shifting sands of Google method searches.  It would be handy to 
have all of that distilled in a channel driver that took the correct 
arguments and went on it's way, and then possibly embedded into 
Asterisk permanently.
