Basically, it's a consumer-orientated device which plays music from iTunes or Internet radio, which you would plug into a hifi or powered speakers. I'd heard of these before but I've been using my old ThinkPad X22 for this duty for a while now, and MPD has served me well. I thought I'd give it a go, and I'm actually really impressed with it.

Physically the SoundBridge is pretty good looking: a sliver and black ten inch cylinder about two inches in diameter, with a large LCD panel on the front. When turned on it found my wireless network, asked for the WEP key, and promptly upgraded its firmware. Once all that was done, it let me select from two libraries: Vicky's Music or Internet Radio. Vicky was running iTunes on her laptop which exports the library over DAAP, so I listened to Tori Amos whilst I explored the Internet Radio options. Then I listened to the most excellent Groove Salad on SomaFM (apparently the #4 station on the Roku Radio charts). At this point I discovered that there was a SoundBridge link in Epiphany, the SoundBridge uses mDNS to publish the web control panel: a useful application of clue from Roku. Then it just got better. The SoundBridge will stream from DAAP and UPnP servers (they pimp mt-daapd and SlimServer), and announces the web interface over mDNS and UPnP. There is a web site which indexes Internet radio streams, currently it has over 5000 entries. This site uses a Java applet (currently only tested in Windows though, I haven't installed Java yet) to talk to your SoundBridge so it can show the currently playing station and tell it to play another station. Then I discovered this in the manual.

Geeks - read this. The M-bridge has a command line interface that you can telnet to for piddling abut. You will need to telnet to port 4444. Type "?" at the command prompt to see a list of commands. ... M-bridge has a built-in UPnP AV "media renderer". This protocol can be used to control the M-bridge from your own software.

The SoundBridge supports both a custom protocol (documented in a 200-page PDF) and the standard UPnP protocol for controlling it. They even documented the signals the remote control uses. This is probably one of the most hackable "consumer" devices I've seen for a long time, short of the N800. Well done Roku, you've created a damn neat product which actually does just work out of the box.
