You pretty much have to have a wrapper script to do this.  It could be as
simple as having a 'screen -X setenv SSH_CLIENT $SSH_CLIENT' in the
wrapper, but that would only update screen, not any shells or other
programs already running inside screen.  The best complete approach I can
think of does involve writing to a file in the wrapper and having
everything else check that file periodically.
