Adeona - Open Source location tracking for your laptop

First their was LoJack, no a new open source solution for tracking your portables - Adeona. From the project... Adeona is designed to use the Open Source OpenDHT distributed storage service to store location updates sent by a small software client installed on an owner's laptop. The client continually monitors the current location of the laptop, gathering information (such as IP addresses and local network topology) that can be used to identify its current location.
