When using rsh, I just do:

remsh otherhost "DISPLAY=$DISPLAY command"

With rlogin, you could try to take advantage of rlogin passing the TERM
variable to the remote host.  A sequence like:

on localhost:

$ TERM=$TERM/$DISPLAY
$ rlogin otherhost

on otherhost (before the actual value of TERM is needed):

DISPLAY=`echo $TERM | sed -e 's;^.*/;;'`
TERM=`echo $TERM | sed -e 's;/.*$;;'`

You could expand the whole notion and use appropriate code on each side of
the connection to pass just about any values you wanted.

Personally, I wish rsh and rlogin would just pass the entire environment, and
let the remote host set it's own local stuff, with everything else remaining
the same.
