It would be hilarious to hack that thing, and right when some perv is going full stroke have it start screaming out 'HELP HELP POLICE I"M BEING RAPED'.
I sent an email to Real Doll a few years ago. I told them that I travel a lot and asked if they had plans for a cigarette lighter adapter to power the gyrating hips. They actually responded. There were, at the time of correspondence, no plans at Real Doll for a travel kit.
