How about capture the output from the device with capturing card? Then videoin and then display it on a quad. Or HTML texture can integrate some stuff too, with little tweaking the code to experiment with enabling plugins… If you need also to send input, then can get tricky.
I can send keyboard and mouse input via Share KM (keboard & mouse) to an android device. perhaps I can develop a android service to start apps and trigger the mouse an key events. I should ask this in an android forum.
has anyone experience with VNC servers on Androids? that would also be a way to control and show apps on a device. how can I implement the VNC window in v4 and is it possible to send mousepositions to the VNC server?
