Hi Matt,

did you try out oddcast with jack? It works really great for me with an
icecast 2 relay server.

Just launch oddcast after starting the jack-server and specify the
channels you want to record from, e.g.:

oddcastv3 -c <config file> alsa_pcm:capture_5 alsa_pcm:capture_6

to record from channel 5 and 6.

You can define stream quality,destination,mount point, ... in different
config files and I think it should be possible to run several instances
of oddcast from even the same input if you need this.

You can download oddcast from

http://www.oddsock.org/tools/oddcastv3_jack/

For an automatic start you could write a small shell-script that's
executed at boot time to start jack and a little bit later the instances
of oddcast.
