multiple servers?

I'm curious if there is a way or how i would have to change moc in order to allow for multiple servers running at once [by one user].

Basically, I'd like to be able to use moc to serve content to an icecast server, but I'd also like to be able to listen to different content and not distrub that. [I'd use jack output, though I'm also thinking about adding a way to have moc use libshoutcast to send content directly to an icecast server]
