* need an easy "switch user" button, like Windows XP.  => central management
of consoles.

* nice to know who is logged in on the console.  "Shutdown" (both
shutdown(8) and kdm/gdm's shutdown) should warn you if someone is
logged in.  (local vs remote).

* nice to be able to save login sessions, like screen(1) does.

* so, we want some consoled that probably has all the functionality of
gdm/kdm/xdm, screen, login, shutdown and possibly ssh.  Maybe it delegates
most of it's functionality to these programs?  Maybe it's just a data
repository that tells these programs who is logged in (?)

* while I'm whinging: X should respect the DISPLAY enviroment variable,
rather than the clunky "X :n" syntax.
