Put this in /usr/local/bin/popup

# Popup message generator
# Written by Dave Hall -
USER=`who | grep :0 | cut -d\  -f1`
export DISPLAY=:0
export XAUTHORITY=/home/$USER/.Xauthority
zenity --info text=$1

sudo chmod u+x /usr/local/bin/popup

then simply run
popup 'message'
as root or using sudo

For more info see zenity --help there is loads of info there

on the machine sending the messages you could just have something like
this kept in /usr/local/bin/network-popup

# Remote Popup message generator
# Written by Dave Hall -
BOXEN='box1 box2 box3' # you get the idea
for box in BOXEN; do
	ssh root@$box "/usr/local/bin/popup '$1' &"

Then simply run 
/usr/local/bin/network-popup 'message'

Even if this isn't exactly what you want, it give you some idea of what
to do.  btw this is completely untested, so you may have to fix bits of
it.  Feel free to ask for more info if you need it.
