We have xinit set DISPLAY to unix:0, and we use the following script to
"leap" to other machines:

#! /bin/sh
#
#   leapto  - shell script for accessing a remote machine under X Windows
#
case $DISPLAY in
	unix:[0-9] )	XDISPLAY=`hostname``expr $DISPLAY : '.*\(:[0-9]\)'` ;;
	* )		XDISPLAY=$DISPLAY ;;
esac
xhost $1
rsh $1 "setenv DISPLAY $XDISPLAY; setenv TERM xterm; setenv PATH $PATH; xterm -132 -n $1"&
