I know that nethunter can do HID attacks on windows boxes (Is *Nix based HID attacks on the horizon?) so it seems to me that P2p ADB attacks on rooted android is the next logical step (https://github.com/kosborn/p2p-adb/) While some versions of android mitigate this attack by disabling ADB when the screen is locked and it can be stopped by disabling ADB there are still a lot of android devices out there vulnerable to this attack. Maybe have the option to install a android meterpreter instead of the app kos's toolkit installs? There is a lot of potential there.
