If camgirls (or partners) could control the device remotely via sensors on a dildo that would be a transformative move I think. But you'd have to create two devices, the receiver (male sex toy) and the transmitter device (dildo). I guess you could make the transmitter with either electronic touch sensors or a mechanical sliding mechanism (like moving the carriage on the Handy) - the advantage of a mechanical solution is it would be easy to create precise realtime movement syncing, but the disadvantage is it would really only be for handjob simulation.
I hope someone is investigating this concept in some form.
