Did not your accessible SVG example use a lot of ARIA? Is it then 
"natively accessible"? I think we speak past each others here. My 
perspective - and that (I believe) of John, is the user's perspective: 
Regardless of the method, there should not be any form of (confusing) 
duplicate content. So we *could* duplicate the content (e.g. by 
supplying 'alternative text') as long as the user don't perceive both 
the original and the duplicate.

There is a problem here: We can't compare a longdesc="" to iframe. 
Longdesc is just a link. Thus: a link to alternative content. The 
representation of the longdesc link is more an extension - and thus a 
kind of - short alternative text.
