Need App to display changing message on user's desktop

I've been trying to find an app that will run on a user's desktop and
display the contents of a text file that lives on a server. These
users are LTSP client machines running a fluxbox GUI desktop. Message
display in a movable window would be great but might be able to use a
crawler, or ticker tape type of app. This would run on an Ubuntu
(Jaunty) server.

Thanks!,

------Begin simple application---------
#!/usr/bin/wish

# Set the filename here:
global file
set file "/usr/local/etc/messagefile"

message .message
pack .message -fill both -expand yes

proc GetMessage {} {
global file

if {![catch {open $file r} fp]} {
.message configure -text [read $fp]
close $fp
}
after 20000 GetMessage
}

after 20000 GetMessage
------End simple application---------

You'll need tcl and tk installed. This application rereads the message
file every 20 seconds (20000 miliseconds).

Assumes the LTSP client machines are running apps on the server itself
(this is the usual arrangement).
