Google Earth + Battleship = ???

What's the name for these things? Enhanced Reality Games? Augmented Reality Games? At any rate, some crazy kids have come up with a brilliant fusion of Google Earth, Battleship, and GPS tech. I think you could figure out how it's played, if you thought about it a little bit, but here's the details:

One person places their ships using Google Earth and the other person goes out in the normal world with a mobile phone, a GPS connected to the mobile phone. The phone has a small Python script on it that reads the GPS and sends the data to the game engine, which then updates the Google Earth KML model showing the current state of the game grid. When the player who's trying to sink the ships wants to try for a hit, they call into the game engine and say "drop". The game reads back the coordinates at which the "peg" was dropped and shortly thereafter, the other player will see the peg appear at the coordinate it was dropped. If the peg hits one of the ships, it's a Hit, otherwise it's a miss.

"Damn" is what I have to say about that. Imagine if this catches on; it could be one really big massive game involving people from all over the world. I could place a submarine randomly somewhere in the world and challenge the entire Earth to try to go find it. Then – wait for it – tell them they don't find it within 24 hours I'll detonate a nuke. I'd better call Jerry Bruckheimer fast. This idea is ready to pop.
