Bluetooth enabled devices can do this but is probably overkill. A couple of friends have their Bluetooth enabled Cellphones connected to their laptop computers so when they walk a certain distance away from the laptops carrying the phones the laptops kick in the locked screensaver.

Could do this with a PDA as well as laptops. Or any two bluetooth devices.
