Until now, toothing has been mostly a British phenomenon. But Jon recently added a new international toothing category to his forum. And quickly, several people began posting, looking to see if anyone in Mexico, the Czech Republic and elsewhere was into toothing.
I can only wonder what's next? Next generation phones will have GPS built it, and more powerful communication protocol called UMB, plus EDGE and G3! I'm sure a mobile matchmaking vendor would exploit these technologies to create a service that would notify you if a match walks into the room. Who knows what's next!
