Anti theft for Tablets

Hey guys, I am looking for a app that will allow me to track my tablet's location in case it gets lost or stolen. The problem is that it is a tablet, and it seems all of the apps I can find (except "prey" which just flat out didn't work) want to use sms to request the gps location from the phone. Obviously my tablet does not have sms, so I need to find one that uses push notifications. (also it would be nice if it were free or at lease a one time fee, not this monthly subscription BS)

It should work that when my tablet receives a push notification, it doesn't actually display a notification. Instead it starts up a background service that will read my GPS location and return it to be displayed on a map.

Is there an app out there for this? Or am I going to have to make this one myself?

 

no one else has put a gps app on their tablet to protect their $$$ investment?
