the gamekit over wifi documentation talks about local wifi and that it\'s built on top of bonjour. Does that mean it does not work over the Internet, locating user/players i
YES, Game Kit can be used to connect peers over Internet.
BUT in this case your application must respond to peerPickerController:didSelectConnectionType: and handle all your private handshake protocol to discover peers and establish communication. A web service on your server is also required (unless users type in their IP address).
Good luck Sam!
