Opportunities for education. I think the overhead of having to
continually create and maintain different mailing lists (and
point all the update announcements at different places per release,
etc.) isn't worth it.

We could go down the RHN route.... most general package updates
aren't announced, and data is pulled from the update tool. How's
that advisory-in-pup work going?
