how to remote control android app from another android app

[oggie]

I have a nexus q. I would like to be able to control the nexus q running the subsonic client from my android phone. The idea is to have the nexus Q running in one room with subsonic and and be in the other room with my phone to control it.

I really want to duplicate the same functionality as the nexus q and google play, but do it with subsonic instead.

Any way to do this right now? I suspect that I could probably install an android remote control app on my phone and nexusq? Too bad this wasn't built into subsonic.
