Yes, sorry, I didn't supply enough details.  Basically its me singing 
over a pre-recorded music track streaming into a shoutcast server (which 
I already have running remotely). So basically I need to mix a 
prerecorded stream with my voice and broadcast that to an external 
shoutcast server.

Mumble is interesting and I can think of some creative uses for that 
with SecondLife but thats overkill for what I need now.  I'll have a 
look at darkice and B.U.T.T.  In the past I had issues trying to figure 
out how to get the stream *into* BUTT but I'll have another look.
