Nice! I have great plans for my Pi. Get a Squeezebox client going on it and run that headless, controlled from my phone. Simple first job. Then write some kind of web app to send commands over RS232 to my DSPs and/or 568. This is more for fun (and get me learning python maybe) than for actual usefulness. Although, being able to change volume from my phone would be good, then I could ditch the MSR and do it all from the phone.

Cinema: DSP5000 (18 bit), DSP5000C, DSP33, 568.1, Quad L-Sub
Music: DSP5000 (24 bit), MS200 + Reviver, Roon
