Bluetooth wouldn't work so well for stuff like follow-me. With these remote when you hit 'follow-me' I know they start with a low-power signal and increase it until it finds the first 'hit', then locks on with it at full power. Fiire said this was part of the stuff they did custom for their remote to let you carry it around the house. You can't do that kind of low-level signal control with Bluetooth, so you'ld have no way of reliably pairing to the closest device.
