This technology is a really prickly issue. I guess it is appropriate to go very slowly and carefully.
There are wrist watches available now that can mate up to the receiver, so that all the wearer has to do is glance at their watch and they know where the dog is. As I understand it, the wrist watch must be in reasonably close proximity to the receiver... for now.
Who knows where this technology will be, in terms of remote capabilities, in the future, with cell phones and who knows what?
We can operate drones and conduct combat missions, missile attacks and such, right now...from half a world away. The drone pilot is in a secure facility in the USA and the drone is flying in Afghanistan. Who knows where this stuff will be ten years from now?
