Hi,
R.mote is not currently under active dev, but pm me and we'll take it further, I am motivated to move this forward, It has huge potential, but I severly lack of time to make it move forward, so if you have a real project, I think it will help.
As for bluetooth, this is not really how it was conceived originially, R.mote is meant to totally remove the physical bind between the controller and the machine, so you can take control of something that is happening on TV for example. But I hear you and I agree it's something that R.mote should consider for a flexible system when it's going to go live.
Bye,
Jean
