(Not the parent poster) Reddit has /r/sdr which has some good resources; me I used antirez's plane-tracker, then wrote some code to listen for buttons being pressed from remote-control buttons. These buttons are pretty cheap and reliable, and the batteries have lasted for a year or so now. You hit the button in the bedroom and the PC in my office plays "siren.mp3" over the speakers, for example. Even now I've had my wife/child summon me via presses.
