Passing DISPLAY across an rlogin isn't very hard; it simply requires
overloading TERM.  I use this script (which I call xdsp) to pass it
across:

#!/bin/sh
TERM=xtu.$XDISPLAY
export TERM
exec rsh $*

The following code in my .login picks it up:

if (($TERM =~ xt?.*) || ($TERM =~ xt.*)) then
  setenv DISPLAY `echo $TERM | sed 's/xt[^.]*\.//'`
  set term = xterm
  setenv TERM xterm
endif

Under X10 I didn't need the sed; I could do everything with the shell.
Under X11 I need the sed to handle the foo:0.0 syntax.
