Re IFRAME: the url for the iframe can be loaded dynamically at any time via
scripting, and does not require a visible screen element. At least that's
what I've read.

Newer _javascript_ can load xml files - which I had no idea, but man its
cool. If you can make the document you are getting an XML document you
can try this:
make a variable - where to get the xml
var xmlsource="http://www.yoursite.net/newsEngine/index.cfm?s=2";
then build an xml document loader (yes it works on firefox and mozilla -
I wouldnt know it if it didnt :-D )
if (window.ActiveXObject)
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM")
else if (document.implementation && document.implementation.createDocument)
var xmlDoc = document.implementation.createDocument("","doc",null)
then load it
if (typeof xmlDoc != "undefined")
{
xmlDoc.load(xmlsource)
}
after that you can do normal DOM stuff on it i.e.
tickerobj = xmlDoc.getElementsByTagName("xmlticker")[0]
It's a really great trick I have used it several times. I dont think it
works back to netscape 4 (or windows 3.11 for that matter :)
I learned this by ripping apart this ticker script

Rememeber to set cfcontent type to text/xml.
Hope that helps
