As an aside, What I really need for this system is a wall-switch that doesn't clobber the state. Right now if you cut power completely (use the wall switch) it loses all it's last settings and turns into roughly the visual equivalent of a 60w incandescent bulb. I'm trying to decide the best way to do this, the easiest would be a raspberry pi. I'm thinking there must be some way to do it with a much ligher thing like a xbee module.
