PreyProject is a complete anti-theft suite with Location (supports GPS and GSM triangulation), Camera, Unlock, Data Wiping and some other functions, Standalone version is completely trustworthy, It basically checks a file on your server and if that file gets deleted, starts sending reports to you. (or you can start the alarm with SMS message)

It is open-sourced, standalone and already compatible with GNU/Linux and Android so I think It wouldnt be too hard to make it work on Maemo. It's a good and stable alternative to SMSCON and it supports server file check and data wipe.

If you can't do anything about it (ie you're not a developer) you can at least vote for it: http://prey.uservoice.com/forums/162...or-maemo-meego

edit: Sorry for wrong category, I cannot move it myself, please someone move it to Applications for me?
