It could be done but these sort of things require a monthly charge. The company has to provide it's own computers to server as hosts which all players connect to. No player hosts his own game. This also make it incredibly hard to cheat so that's good too.
Meanwhile, Xbox live serves not as a hosting service but as a matching service, allowing you to find other Xboxes which are willing to host. This requires minimal facilities.
