There are many network music players...Sonos devices, Slim Devices's Squeezebox, the Roku SoundBridge, to name a few. These all have network protocols that permit external device control. Many obey UPnP protocols.

I personally have two Roku SoundBridge devices and have drooled over the prospect of controlling them with my 770. I have developed a controller for the SoundBridge devices and am adapting it to the 770. The problem is that the controller is written in Java. There is a JVM for IT 2005 (I was using jamvm) but nothing yet for IT 2006.

Once something like jamvm is implemented for IT 2006, I can continue the interface work. I had things limping on the 770; the interface was too "heavy" (resource intensive) for the 770. SOmething simpler is in order.

Anyway, these things are definitely possible. It's exciting to think about using the 770 to control other household devices, especially music players.
