The rough script below could be converted into a "gnome-wall" that is 
called at the very start of rc0.d and rc6.d, followed by a long sleep, 
to warn all users of the impeding system interruption.

Of course, this is a rough hack. 

Ideally, GNOME would simply have a way to catch all wall messages 
(such as those issued by 'reboot') and to display them via the 
notification area.

#!/bin/bash
for PID in $(pgrep metacity); do
   DISPLAY=$(cat /proc/${PID}/environ | tr '\0' '\n' | grep DISPLAY | sed -e 's/DISPLAY=//')
   XAUTHORITY=$(cat /proc/${PID}/environ | tr '\0' '\n' | grep XAUTH | sed -e 's/XAUTHORITY=//')
   zenity --info --text="$1"
done
#EOF

PS: the above script was hacked by LTSP developer Scott Balneaves.
