Well what might interest you is a new user demo for AGK2 - it uses a PC and an Android device to give a VR experience using that Google cardboard headset thing - so you'd have your Android phone over your eyes as a VR headset, and play the game on the PC.
Not strictly what your looking for, but it does mean that sharing the screen render from the PC to the Android phone must be reasonably quick. The PC acts as a host and sends multiplayer style data back and forth between PC and Android... I think hosting a multiplayer game on an Android device should work - but the problem is probably an Android devices upload speed, it won't be as fast as a PC, so using a PC server is the norm. I guess it depends on the game, I mean how vital is the other players camera render and upload speed... would it be possible to use raw data and just render it locally instead, which would be far more efficient.
