Streaming to a SHOUTcast server with Pi

I've had a search around in the forums, there are people doing similar projects to what I am hoping to acheive, but in reverse and using the Pi as a server as opposed to an encoder.

What I'm looking to do, is using my Model B Pi (512MB Edition), capture audio from my USB sound card device, and stream it to a Shoutcast server to broadcast.

I've heard of "MuSE" however from what i've looked at, it appears more of a multi-track sound editor rather than stream encoder.

I could just be looking in the wrong place within the software, but I thought it's definately worth asking here, there's bound to be somebody who knows what to do.
