Comment 1 for bug 352307

It just occurred to me that this might get much more tricky than I thought. update-notifier messages are system level, thus (1) only admins will see such a note if I'm not mistaken, and (2) once the first admin ack'ed it, other users won't see it any more.

What we want is a per-user notification. Maybe we can abuse the messaging system that gnome-screensaver has, or otherwise just use libnotify-send. I'll ponder this a bit.
