This part is wrong: "It is not possible to find a cross-browser way of applying a background image to this scrollable area.". I know that's rubbish because I set a bottom right background image on one just the other week.

This isn't a substitute for an iframe. Iframes get remote pages and loads them in - this doesn't.
