Actually, if we just would disable utmp recording of xterm etc, we would be
   fine. I've never understood what the value of this was... either you are
   logged in at console, start X11 from there, then you're registered at the
   console. Or you login via xdm, then xdm has registered your session.
   
   Single xterms shouldn't have the login session capability any more than,
   say, a subshell started from your sh or csh.
   
   But I guess many people won't follow me there.


nope, i don't think so.  you're forgetting several things:

	- remote sessions that are simply xterm's to a remote display, not
	started with xdm (think "ssh -n host xterm &").

	- talk(1), write(1), etc., really like to have a tty attached.

	- some people like having every shell they are running entered in
	the utmp file...
