asterisk users - Nov 2009 - DIDs > PBX > Multi-channel balanced audio output?

There came up an interesting question on last weeks VoIP Users Conf
call. http://vuc.me. An internet broadcaster wanted to be able to take
a number of "phone calls" and bring them into a traditional audio
mixer
where each call was a separate balanced audio source to the mixer.

Let's say that he might need 8 simultaneous calls. Is there a way to
set this up using a single Asterisk server and the monitor process to
send the various call streams to a multi-channel audio interface card?
He wants to mix them external to the server in the audio console so
there's no MeetMe involved.

It's perhaps more obvious to suggest using small format hardware
(ALIX?) and a USB audio interface to effect a single line interface.
But then extending to more tha n afew lines might get unwieldy.

Any ideas?

Michael

Jackaudio? That would require 1.6.
