How is that worse that two windows with the identical URLs? And how is the meaning of "same" different in those two situations?

OK, I guess his comment can be taken to mean that there is currently no way for an iframe to be divided into two pieces (outside of IE region experiments) with partial documents in each iframe. But that seems pretty obvious, and obviously not what I was talking about. A document is always a copy, of some patterns of ones and zeros on a hard drive somewhere else. It is identified by its URL, and that _can_ be in two different iframes at the same time, each with its own "rendering" of the document at different widths and scrolled (by the user, for instance) to different positions.
