Stream internet radio via router

Using latest Shibby build on a Cisco E3000 (soon to be upgraded to a E4200) and wanted to know if possible to stream internet radio stations via media server

I have seen some articles about mpd but not sure if this is included in any versions of Tomato and don't want to play the music on the router just allow other devices to play the internet radio stations in same way they can play mp3 tracks from USB drive plugged into router

Is this a simple task and does anyone have any quick guidelines...
