My hubby is a BIG fan of the Tour. He was wondering the same thing. Apparently there is some place on the web you can pay $20.00 (I think) and watch it. He is currently camping nearby and only has his netbook with an aircard. We tried testing his ability to watch this by viewing some of the clips on YouTube. Unfortunately in our case the clips were buffering so badly either as a result of the connection or YouTube itself, that he gave up any hope of paying the $20.00 and watching it.
I'm recording it at home on the DVR so when he gets home he can see it.
