I have seen software that loads and hides on your computer........If you do not change it, and it attempts an access to the internet via a different telephone number, it will call you on your home phone) and tell you the new number, and you call the cops.

The rest is quite technically possible, and is already being used on motor vehicles.........it costs money though?

We all know that quality is being sacrificed for price/cost so what manufacturer will include this other than an optional extra.

Another thought.............how do you tell the device that it is now "home"?, and what if you don't bother?.........is this Gates trying to justify his XP security crap.........costs me a phone call every time I have to re-install

Just a few thoughts
