Extract the authorization info (in numeric format) and mail to the other
user (you may want a secure email connection, though )

xauth  nextract - $DISPLAY | mail friend@example.com

friend@example.com then saves the mail in say,  "secret", strips the header
and does

xauth nmerge secret

That should do it.

Or, if you have rsh access to the remote end, in one shot
`xauth extract - $DISPLAY | rsh remote_machine_name xauth merge -`
 
(from man xauth)
