Scripts in SL that automatically SMS you in the real world. Scripts that read Twitter posts and parse them to have your avatar do appropriate things.
While it might originally start out as a toy (teledildonics, anyone?), this sort of thing could provide that “office” feel to virtual officemates. Need to walk down the hall to the office cooler? Your avatar can – and your RL officemates get a text/IM of your convo even though you’re worlds away.
This kind of integration of the virtual and the real could either be a great big distraction – or provide yet another big “R” in the way things are done.
