I have bought a new toy that is connected to the computer. It is a Pinnacle SoundBridge, which is the same as Roku SoundBridge. It download and plays music from my Ubuntu Server and can also play internet radio. I have installed Fire fly media server on my server to stream music using the daap-protocol. There is an Ubuntu/Debian package in the default repositories that is called mt-daapd, which is the old name of Fire fly. A nice thing with Fire fly is that it converts music files that are in formats that SoundBridge doesn't understand so they can be played anyway.
