Shoutcast Server over Lan

[ViViDboarder]

I'm at a university right now and I'd like to have a shoutcast station. I've found that I can connect via the Winamp DSP plug-in just fine to my server running back at home, but the bandwidth isn't much there. I'd also like to host a server from my computer here. Unfortunately, the ports for Shoutcast cannot be forwarded to me. Is there anyway I can broadcast over LAN instead of the internet? This way anyone on my domain will be able to connect to my station without having to worry about ports? I know nobody over the internet would be able to listen to me, but I would also broadcast to my other station.

Thanks,

Ian
