I am anything but tech savvy, but I do remember reading an article many, many moons ago in which they claimed that the Russians had developed "devices" which could be used for exactly such "internet encounters". The bloke plugged his "vagina-like" device into his PC and the woman, on the other end, plugged her "phallus-like" device into her PC and then they... got intimate.
I never followed up on the story, so don't know what became of the project.
