I would think that in practice, IFRAMEs would, at least
psychologically, be significantly less useful to web app developers.
This is due to the fact that frames are conceptually more difficult to
properly position and size to accommodate any dynamically inserted
text; are more cumbersome to pre-populate with data on server-side
(extra HTTP roundtrips or opaque data: URLs). Also, are renderer
implementations actually ready to handle hundreds of seamless IFRAMEs
on a page with the performance footprint not exceeding that of spans
