I came across it this week. It is a software that is similar to the lowjack system for laptops. It works in the same way after when it is stolen the computer will broad cast out and then it can be located through the IP address that it is sent from. Through knowing the IP address you can get down to the physical address at which the computer is located though the internet service provider as well as any police department should be able to help you with it. Best of all it is free.
