I was reading the other day about an anti-theft system that is available in high-end cars. If the car is stolen, the GPS system checks with the GPS satellite and determines where the car is. Then it uses it's built in cell phone to call you and give you the information. I suppose it could also call the cops.
The same tecnology could also work with a cell phone, a laptop, a boom box, a boat, a television set, a palm pilot or just about any other device with an electrical system. Think about it. Your house gets robbed, and your microwave rats on the crooks. It's enough to make them go back to rustling cattle! Come to think of it, I remember something about a little chip that could be implanted under a dog's skin so that, if lost, he could be sent back to his proper owner. That would work with cows.
