Hey man,
I'm afraid I haven't used my N900 in ages (since I got my N950), so updating the apps I wrote for it has taken a bit of a back seat; especially with all the work I've been bogged down with of late.
I'm not sure how good your programming background is, but if you want to try and tweak the code yourself, or look at writing your own override file, then you're more than welcome to. The code is on gitorious.org (see the first post) if you're up for it.

Otherwise, I'm afraid I am not likely to release any updates for this application, up to the community to maintain it from here on out. It was more of a demonstration to prove that it was possible to implement a proper Lock-On-Launch security layer on Maemo than aimed at being a consumer application anyway.

Regards,
SPARTAN
