That's actually an excellent idea. 

If you're looking for a frame of reference, you might want to take a look at 
VPIM (Voice Profile for Internet Mail)... standards for exchanging voice 
messages between servers over the internet.

You might also want to take a look at AMIS (Audio Message Interexchange 
Specification), a standardized way for exchanging voicemail between remote or 
different manufacturer's systems.

Unfortunately the analog version (which is obviously not what you want) is the 
only thing I know anything about. One server actually calls the other, they 
exchange some DTMF, and then the first server actually plays the message to 
the second. It might give you some interesting ideas, though:

There's maybe an FTP-based version of AMIS also... dunno.

Just some food for thought.
