I don't have the time or the exact knowledge - obviously, I'm here to try to find answers for my own things -- and seeing very few answers and a lot of questions.

However, I was just messing with javascript scrolling / news crawls, etc.  and one of them used an i-frame, I think.   You could put anything you wanted in it - it was just this window on your page.   I suspect that would solve your problem.  One of the javascripts sites was nice in that every different thing had a demo so you could see it.   Sorry that I can't give you more, but that should work for you.
