What I'd suggest is that you set up an Icecast server on the LAN at your
station, with the audio output sent to your broadcast mixer. Your remote
studios can then connect to you with any Icecast compatible client (such
as darkice, or the 1.9.x development version of Mixxx). Of course you
will have to make sure that the IP address of the Icecast server is
accessible from outside your firewall (e.g. by using port forwarding on
your router).

You will have to set an appropriate buffer size to allow for the
possibility of short connection drop-outs, because TCP/IP is designed to
guarantee packet delivery, rather than guarantee that packets arrive
with low latency. This might imply that your remote studio starts its
stream a couple of seconds ahead of the re-broadcasting start time, or
starts with a fade-in so you can cover the gap by crossfading a jingle
at your end.

There is some support in Campcaster for re-broadcasting an Icecast
stream at a specific time. For example, play a pre-recorded show from
9am to 10am, then at 10am automatically switch to the stream from the
remote studio. However, I'm not sure if this feature is working reliably
yet in the forthcoming 1.6 release, so it's best to check that.

The alternatives to using Icecast could be Netjack, or EBU N/ACIP which
is based on SIP. I'm not aware of an open source implementation of
N/ACIP other than the original ACIP reference implementation.

Cheers!

Daniel
