I was wondering about dynamic content in SMIL. I was hoping to be able to
display text that can be updated by an external program and is displayed at
the bottom of each slide in a constantly looping slideshow. It can be based
on either an external source and bringing in the text using <text
ref="blurb.txt" ... /> or could be SMIL+XHTML and update the text in the
tree directly. 

I read the message replying to "How to control dynamic content?"
(http://lists.w3.org/Archives/Public/www-smil/2000OctDec/0025.html) but the
data is most likely going to be loaded locally, though if need be we could
probably set up a local web server on the system. 

I'm not against scripting however I'm uncertain as to what scripting
languages most SMIL viewers support (do many of them have ECMAScript support
for example). Even with scripting is there a way of informing the SMIL
viewer to clear the cached object and reload it from source (assuming we
aren't using the second approach to use XHTML and update the DOM Tree with
the new message).
