Tools or scripts for tracking a stolen or lost Mac? Actually I do use the prey project but was wondering about other tools or scripts one could use to find back information about a lost/stolen Mac.

With features like:
-Getting the ip address or any other localization information.
-Triggering the webcam remotely.
-Protect/destroy personal files remotely
One of the more popular ones is Lojack, a pretty well-respected software program for both Mac and Windows.
