One nice project that can evolve to solve the issue i've raised is the one called Maenotify (Desktop Apps Voting Thread [N900 Coding Competition] ) presented by b0unc3.

I think it would be nice if each info piece showed in the "lock screen" could be moved anywhere (or removed) by the user as it was a widget...

It also opens a whole world of possibilities to widgets be created focused in the "lock screen"...
