[NMLUG] Getting the message out (to an X user)

[havoc at harrisdev.com (Jody Harris)]

I have a "daemon" that runs a task in the background.  When the daemon 
is finished, I would like it to send a message to the desktop user 
(running KDE 3.2 over X) to restart the primary desktop application. 
(Unfortunately, the software cannot be configured to periodically scan 
for new files, so the only way to "find" them is to close the app and 
restart it.)

How I can I a script (effectively a console user, with no shell) send a 
pop-up message to another user (known, default user, in this case)?

Thanks,
jody
