It really does pay to have a brandable rss newsletter.... Feedburner will never do your content justice. I've been contemplating getting those folks at icontact to generate me a custom newsletter with rss updates for an absurd some of money. This really totally rocks.
So that's how it's done. I had the same problem when I designed a website sometime ago with flash content. I decided to scrap the idea after I couldn't figure out how to make it work properly.
