Well, mainly, I was thinking about them because I was playing around with using the camera button as an on/off switch. I figure if you're using Lanterne, you're probably not wanting to take a picture.

I dislike the idea of one app messing around with another app's "gconf" settings; just temporarily killing the app, and restarting it when Lanterne ends, seems cleaner somehow...

In any case, this would certainly be an optional setting in the preferences, that would not be enabled unless the user asked for it.

(BTW, is it possible to continue to monitor the status of the hardware buttons when the N900 backlight goes off? I was hoping to be able to enable the LEDs while the screen was still dark, but it seems that isn't possible...)
