We can run the X server with the option "-nolisten tcp" set. This option caus

the X server to not listen connections from any client. To use this option,
simply add it to serverargs variable in the /usr/X11/bin/startx script.

... then use Xforward to listen on port 6001 to forward X traffic to
the UNIX domain socket the X server listens to.  Xforward will pop up a
window asking whether you wish to accept the connection or not,
allowing you to have your cake and eat it too.  Xroute can be coaxed to
do this as well.
