I think that disabling or blocking the TCP listener on port 6000 makes 
no difference to ssh.  If DISPLAY is set on the local machine and ssh is 
started with -X, the session on the remote machine will have DISPLAY set 
automagically.  The remote DISPLAY refers to a socket that ssh is 
listening on, not X, and anything going to that socket is passed by ssh 
to the local DISPLAY socket.

You also shouldn't have to play with xhost as ssh fakes (or proxies) the 
authentication.

If sshd_config says X11Forwarding no, I think you are out of luck since 
this should override any client side settings.
