Write a shell script called mpg123, located in /usr/bin or 
/usr/local/bin that spits audio out on it's STDOUT in the correct 
format.  I think the format is 8khz, mono, 16-bit.  You can set up music 
on hold with mpg123 the just do a px -axwww to see what parameters 
Asterisk uses to start mog123, read the mpg123 man page and then make 
your script output the audio in the same format.  Or you can just look 
at the Asterisk source code for the options.

It's not hard to write the script.  It's hard to make the script do the 
right thing when you have network problems and get disconnected from 
your streaming source.
