Without knowing exactly why, my feeling is iframes are broken. If not.. why arent iframes used in say yahoo and google customisable home page mashups?
Differences :
granularity - share one div, not whole page
scope - how should javascript interact between the inclusion and the whole page? [ Im not sure.. this wasn't on the radar when iframes were designed I guess ]
