I would check for established VNC connections this way:
netstat -tape | grep ESTABLISHED | grep Xvnc
As for warning connected users. If you see there is an established vnc session on port 5902, you could simply do:
export DISPLAY=:2.0; xmessage -center -timeout 60 -file shutdown.txt > /dev/null 2>&1
You could create a list of established connections, translate it to active displays (5902 -> 2.0 | 5903 -> 3.0 ...) and send out a message.
Hope it helps

Thanks for the answer :)
I have made a file "ww" that is executable containing:
"netstat -an | grep ESTABLISHED | grep -v 127.0.0.1".
Is this sufficient to tell if any are connected / logged in?
Is there any way to tell people logged in via vnc that I am going to
reboot the system? something like 'wall'?
