Hawkeye in tennis

I was watching the Nasdaq-100 Open Women's final between the Russians Sharapova and Kuznetsova (which the latter won easily, by the way), and what do I see? They were using Dr. Paul Hawkins' Hawkeye technology. The players could challenge any line call they disagreed with. What's even more interesting is that their use is similar to the solution I had suggested last year.

Each player will receive two challenges per set to review line calls. If he or she is correct, he will retain the same number of challenges, but if he is incorrect, one will be lost.

My suggestion had been to allow teams to challenge as many decisions as they want so long as they are correct. If they are incorrect on two occasions, they would lose the right to challenge any more decisions.

While we wait for the men people running ICC to grow balls (and common sense) and start using Hawkeye to aid the umpire, the tennis world has already done so. Granted, they're using it to determine where the ball's been instead of where the ball would have been, but Hawkeye and other similar technologies (the red strip marking the wicket to wicket area, for instance) are not being used to determine that either (ie, where the ball has landed or hit the player's pads). It disgusts me.
