I will also throw in an idea.
I don't know if Russound's RNET is proprietary, but I'm running into limitations with trying to stream external devices WITH META capability.
If your gizmo was able to talk to older CAM & CAV controllers, and the current C-Series, I for one would be all over that.
I know I have some iPxd options, but being able to feed multiple sources of Pandora, Spotify, etc out of a single device would be a huge plus.

Feel free to contact me if you're still looking for beta testers.
