You should be able to do that using Liquidsoap. A single running
liquidsoap instance can accept multiple icecast/shoutcast source
connections, create a single stream out of them and stream the result
to Icecast.

You can contact us at savonet-users at lists.sourceforge.net or lookup
online at http://savonet.sf.net/ for more details..
