Is this FOAF specific? Or just a general thing with authenticated views 
of Web sites.

http://www.flickr.com/photos/danbri/ is my Flickr photostream (and 
hopefully soon an :openid for me too). When I'm authenticated it offers 
me more information than you'll see (and more action possibilities). 
Some of that extra info might be linked versus embedded, some might be 
in HTML (or RDFa or microformat).

Relatedly I was discussing with TimBL a bit lately the issue of how 
different the representations of a document can get, before you really 
ought to be using different URIs. This came out of practical questions 
around Tabulator behaviour, since Tabulator rigs your browser to say 
"hey, gimme the RDF version", meaning you miss out on seeing HTML 
documents that are content-negotiated with RDF variants. Tim argued that 
the HTML and RDF ought to be available from different URIs. Perhaps 
there's some common 'best practice' here re authenticated views of pages 
too. Or as you suggest, just need for a bit of vocab to describe the 
various deployment idioms that are already out there.
