Probably theater.
I was looking into an OhMiBod for fun with a friend.
The vibe is music or smartphone operated, costs $5 to activate the app on a phone.
You have to sync by Google+ account. No anonymous control allowed.
The app allows physical control (tap to send a vibration), or choose from pre-set patterns.
If the phone enters sleep mode, another app takes over, or the save screen pops up then you lose connection and the vibe shuts down.
So still in beta as far as I'm concerned.
Nothing I heard would indicate "tip amount = vibration".
However, OhMiBod is part of RealTouch: a company that makes teledildonics for cam girls. So if anyone would have a custom program for cam girls, OhMiBod probably has it.
I am more leaning toward a Zeus and Hera pair from LovePalz, but they are like $200 a piece! ouch… maybe for Christmas… maybe… .
