I have also now created a website to track my n900 and if it gets lost/stolen I can tell it to do various things.

The tracking service is intended at this point for people interested in developing an application to use it, or people who are happy playing in scriptworld - I have included the scripts that I used to get it working and that run on my n900 now

See http://talk.maemo.org/showthread.php?p=627494 for details.

Cheers,

Ben
