Well You can look at  update-notifier-common specifically,

When I ssh into machines with that configured I see somethign like:
498 packages can be updated.
0 updates are security updates.

Failing that I think:
	apticron - Simple tool to mail about pending package updates
	cron-apt - automatic update of packages using apt-get
Are packages that can automatically do an apt-get update and then send an email
basied on what's available.

Yours Tony
