I think this is a good idea. Here are some more suggestions:
1. model the updates on sysV init scripts, so they can be started
and stopped/applied and removed as needed by an upgrade;
2. the new updates notification should require deliberate action
by the superlibrarian, else we may be violating user's privacy
(also known as a "phone home" problem).

Can't they just start or end with a number, divided from the
human-friendly name by a - or similar? It really is useful
to have human-friendly names.

Take a look at dpatch if you have a debian system nearby.
http://alioth.debian.org/projects/dpatch/ - I'm sure there's
been criticism of it, but I didn't locate it in a web search.

Hope that helps,
