See Mark Kendall's original response to the topic.  MythMessage 
currently uses an XML template, with multiple fields that are replaced 
through options on the command line.  Right now, there is only one 
template supported, and running `mythutil --print-template` yields....

<mythmessage version="1">
<text>%message_text%</text>
<timeout>%timeout%</timeout>
</mythmessage>

So running `mythutil --message --message_text='blah blah blah' 
--timeout=60` yields a popup that will time out automatically if not 
cleared in 60 seconds.  The UDP listen daemon picks up the datagram, and 
sends an internal event with the message and timeout, which gets 
processed by the main UI window.  It spawns a popup with the message 
and... completely discards the timeout duration.  I'll have to 
investigate this further...
