If this is a workstation, where you can reasonably assume that the
user's display will always be :0, you can just override X access
control for local processes, by using
    xhost +local:
(perhaps in the system's /etc/X11/Xsession scripts)

Then "xmessage -display :0 ..." will work from any script.

(BTW, check out zenity, a prettier and more versatile replacement for
xmessage.)
