Adeona, from researchers at the University of Washington and the University of California, San Diego, anonymously sends data to servers on a free storage system called
OpenDHT. The data, which is encrypted, includes IP addresses, information about neighboring routers, and so forth. If your notebook ever gets stolen you can log into the system from another computer, access the data and notify authorities with it. Working with ISPs they should be able to locate it. The Mac version also uses a freeware program called isightcapture to take a picture of whoever is using the system.
