Have a look at Professor Kevin Warwick of the University of Reading, UK. http://en.wikipedia.org/wiki/Kevin_Warwick
He was linked electrically to his wife although not as dramatically as the OP asks about. From Wikipedia:
"The electrode array inserted contained 100 electrodes, of which 25 could be accessed at any one time, whereas the median nerve which it monitored carries many times that number of signals. The experiment proved successful, and the signal produced was detailed enough that a robot arm developed by Warwick’s colleague, Dr Peter Kyberd, was able to mimic the actions of Warwick’s own arm.
By means of the implant, Warwick’s nervous system was connected onto the internet in Columbia University, New York. From there he was able to control the robot arm in the University of Reading and to obtain feedback from sensors in the finger tips. He also successfully connected ultrasonic sensors on a baseball cap and experienced a form of extra sensory input.
A highly publicised extension to the experiment, in which a simpler array was implanted into the arm of Warwick’s wife—with the aim of creating a form of telepathy or empathy using the Internet to communicate the signal from afar—was also successful, resulting in the first purely electronic communication experiment between the nervous systems of two humans."
