It'll be displayed only during logins, even though it's quite possible

This is just one more feature we're implementing in Landscape, and
in this case it'll benefit even administrators that are not Landscape
users.  If you want to reuse it in different situations, the software is
GPL and it should be trivial to just run it from cron and ask it to mail
the information anywhere you want, for instance.

It'll be easy to run it on desktops too.

Nice ideas!  Thank you!
