At present, I use a special splash screen with my name, address and picture on it as a theft protection. I figure that if someone buys a stolen tablet, they will reboot it at some point.


As to a phone home application: my tablet automatically connects to a sip server from sipphone.com (and google talk too), I got a gizmo account ages ago and simply use the built-in sip client now. When I log to:
https://my.sipphone.com/mysip/app?cl...ipRegistration

from anywhere on the net, sipphone will report back the i.p. of the tablet when it is connected. This would be sufficient for the local police.
