Track Your Stolen Laptop For Free

Just a quick note: I just read about Adeona, a project from the University of Washington that lets you track a stolen laptop for free (of course you have to install it before you have someone steal it ;-)). The Mac OS version can even take snapshots of the thief with the iSight camera, like this one:
I just installed it and I hope that I'll never need to use it. Having some hooded freak messing with my MacBook Pro is just a too terrible thought to bear.
