Ah…ok
Doing some poking around…saw an Arch linux build called OSS
Then stumbled upon Icecast

About Icecast 2
Icecast is a streaming media (audio/video) server which currently supports Ogg (Vorbis and Theora), Opus, WebM and MP3 streams.
It can be used to create an Internet radio station or a privately running jukebox and many things in between. It is very versatile in that new formats can be added relatively easily and supports open standards for communication and interaction.Icecast is distributed under the GNU GPL, version 2.
Looks like IceS might be a good app to use with Icecast
IceS is a source client for the Icecast streaming server. The purpose of this client is to provide an audio stream to Icecast, so that one or more listeners can access the stream. With this layout, the source client can be situated remotely from the Icecast server.
A bundled software already
Or SHOUTcast (It appears as a paid service)
Apparently Rhythbox w/ a plugin can become a DAAP audio server

Apparently there are BOATLOADS of plugins that will allow you to configure and run the server
Even have a webgui
OOH!
