Fast user switching would be alright.

Perhaps GDM can be enhanced to dynamically open and close extra virtual
X consoles, so the user can open the foot menu and click Switch user...

This triggers two actions:
  * lock the current X screen
  * let GDM know another user wants an extra X console

GDM spawns a new X console.  User logs in.  Everyone is happy.

Ideally the greeter would contain a list of already open sessions, so
the user can identify his session upon doing Switch user...  Once the
user chose one of the sessions, the current X console (which, if you
remember well, was at the greeter) should go.

This can be coupled with a change in the XScreenSaver password screen,
that would include a button to request "Switch user" as well.

It's very doable.  I think the two hardest parts are modifying GDM to
support such a thing (extra challenge points: doing it in an
interoperable fashion so KDM and perhaps xdm can also implement this
feature quickly) and writing the "session pager" that would go on the
Greeter.

All is, of course, achieved via startXs or X -queryes, and chvt's.
