 Isn't `xlsclients` the way to discover both whether X is running, and 
whether an editor is already running on it?

if xlsclients 2>/dev/null >/dev/null;
then 
  echo X is running.;
else 
  echo X is not running.;
fi

if xlsclients | grep -q "x*emacs";
then 
  echo x*emacs is running;
  if ps -waxu | grep -q "^$(whoami).*gnuserv";
  then 
    echo gnuserv is running;
    export $VISUAL='gnuserv';
  else 
    echo but not gnuserv;
    echo "Please add (gnuserv-start) to your ~/.emacs";
    export $VISUAL='ae';
  fi;
else 
  echo xemacs is not running;
  export $VISUAL='ae';
fi
