Oh, it wouldn't. I was thinking more along the lines of Jeremy's idea  
of addressing a group of hCards.

As for addressing an specific hCard from outside the document, then  
indeed, we just need a small set of ID conventions. An ID must be  
unique in a document of course, so these should be namespaced in some  
way, so as not to force publishers to rework existing documents. e.g.  
'author-vcard', not just 'author'. The only requirement on parsers  
then should be fragment support, which is already a requirement.
