NOOO!!!!
ssh takes care of the display stuff. What you describe actually sets your
communication outside the secure tunnel opened by ssh as well as opens your
display to outside programs.
bash-2.05$ hostname
falco
bash-2.05$ ssh -X archives

lufthans@archives:~$ echo $DISPLAY
archives:11.0
lufthans@archives:~$
That archives:11.0 actually points back to falco:0, which is where my
original shell started.
BTW, for those that need to open an X display to local X traffic, but
not external stuff use "xhost +local:". Also, if tcp is turned off in
/etc/X11/xinit/xserverrc, then connections from the network aren't allowed.
Apps opened via ssh tunnels are actually local traffic, not network traffic
because they make a connection to the X server via local methods ( unix
socket or tcp? I presume unix socket ), rather than connecting to the X
server via the network.
