This is probably really old, but it's still cool. The Anycom Bluetooth Music Station Converter is an A2DP audio receiver with an iPod dock connector, so it can connect to any iPod speaker set or dock. With this little gadget you can easily stream audio from a computer with Bluetooth (like a Mac running Leopard) to a iPod speaker set (like the Bose SoundDock). And at just $50, it's a pretty good alternative to AirTunes if you already have a Bluetooth computer and iPod speaker dock. It's available from Sprint but it should work with any A2DP Bluetooth device.
