You want the theory or the practice? :)

You can do this, and I've just tested this in IE6 and Moz1.3.
However I remember trying to do the same thing with IE4 around 4 or 5 years
ago and being disappointed to learn that the iframe would use a child window
which meant that it would clip the layered div so that it would appear to be
higher in the z-order when it should be lower.
How IE5 and other browsers will treat this I couldn't say.

Are you using the iframe just for the scroll effect, or are changing what
document is loaded into it. If you're just using it for the scroll effect
you could use a div with CSS to reproduce it.
