Not to be a negative Nancy but I think that pro teams won't find it useful in analyzing games simple because a video deprives you of control. You can't switch tabs, can't go to an arbitrary place on the map and can't increase the game speed. All you can do is watch the game from multiple perspectives, something you can almost do inside the game (press 1, watch for 5 seconds, press 2 and you get the picture).
Amateur players might find it useful when sharing their replays with friends, but how can that be monetized? A lot of gamers are reluctant to pay for premium content like GSL/MLG, I doubt they would want to pay for sharing video-replays with their friends.
Anyway, it's always cool to see things like this, things with a bit of magic :) Good job!
