teledildonics
     
         /tel"*-dil-do"-niks/ Sex in a
        computer simulated {virtual reality}, especially
        computer-mediated sexual interaction between the VR presences
        of two humans.  This practice is not yet possible except in
        the rather limited form of erotic conversation on {MUD}s and
        the like.  The term, however, is widely recognised in the VR
        community as a {ha ha only serious} projection of things to
        come.  "When we can sustain a multi-sensory surround good
        enough for teledildonics, *then* we'll know we're getting
        somewhere."
