while it certainly is an interesting idea, i don't agree with it. Sure it saves launching a satellite by 30%, but consider the satellite (according to this page) is 22,000 miles up, the tower is only 12-13 miles up, it can see considerably less terrain than a satellite...
who cares if they yell to everyone? you're there, you want the game, they want the money, if they didn't then they'd close the store to everyone else, who really gives a crap?
