Isn't the point of vnc that Xvnc is someone's *personal* X server that
she can leave running and come back to from another machine? You even
have to give it a password. Combining it with xdm makes no sense.
What may make sense is when someone starts up X (either by logging in
via xdm or explicitly), the session tries to contact a previously
started Xvnc and if found, doesn't start any clients except a full
screen vncviewer. Optionally start a new Xvnc if none found, this time
populating it with the normal clients (windowmanager and whatnot).
