Not a problem, afraid I still can't find anything on my side that points to battery drain, so I'm going to assume it is something else that you guys have hit on for the mean time. Will also be porting AppLock over to MeeGo/Harmattan within the next few weeks (provided Harmattan does use DBus as much as Maemo) and that will give me the chance to do some more work on everything.

As for Python, I really am not sure if it comes bundled. I had it installed on my phone when I first wanted to use it, but it could well have been there from a previous application install. You could always try installing it manually from the console:
As for Cleven, I'd recommend you don't install it unless you actually have a legitimate reason to be running penetration testing. Doing so without permission is HIGHLY illegal and can land you up in jail very quickly if you aren't careful. Besides, cracking WPA networks (which most people run now) will take way too long on your N900 to be of any use, and I highly doubt you are running a WEP network? Anyway, just my $0.02, good luck anyway
