Distance coaching

The sports article in the New York Times forwarded to us by Dr. Faverty was very interesting to me because I had not realized the positive effects that technology could have in athletics when it comes to rehabilitation.  Also, I am especially interested to see how far this idea of "distance coaching" can work without the crucial "real life" contact between athletes.  I can see the benefits to this sports technology as far as technique practice but will a dependence on this method cause athletes to falter when they are put in the full impact, non-simulated situation?
