I'm not sure if I follow this bit. Do you mean like JSON is a choke point, so the powerful phone/tablet can't effectively communicate with the powerful Kodi gaming system?

I just meant that, for this type of usage - sending gamepad commands, small packets, very chatty - json-rpc is way too much overhead and would be a waste of processing cycles.

I'm evaluating the use of WebRTC for netplay. What if we used this for the virtual game controller? This would have the benefit of being able to stream video to the phone FWIW.
