One way to make this work would be to start a program running in the GDM
PreSession script that causes the user session to exit after a timeout,
or after waiting for a certain amount of idle time, which you could
perhaps get via running a utility like "who".  You can read more about
the PreSession/PostSession hooks in the GDM docs:

  http://www.gnome.org/projects/gdm/docs.html

If you know the user is running GNOME sessions, you could use the
program "gnome-session-save --kill --silent" to actually cause the
session to exit.  If you are using other session types, you'll have
to figure out the similar method to do the same sort of thing.

Rather than just exiting the session, it might be nice to pop-up a
dialog a few minutes earlier warning the user to save any unsaved data,
or giving them the option to extend their session timeout.
