Thanks Gordon. I'll have a play around tonight on my Mac to broadcast a Bluetooth signal and see how quickly the pi picks it up.
If it's within 1s, that's great, if it's longer then I might go down the IR route since I only want to register that a button has been pressed, not really sending any extra data.
