Right, and it's precisely in this scenario where it would be quite useful 
to setup a 'mapping' from the single URI to multiple URLs, but this should 
be a second option to using content-negotiation against a single URL.

I can understand the caution and the same red flag was raised in my 
mind with this suggestion, but I guess it would help to ask if there are any specific 
situations where mime-types are not sufficient enough to describe 
'unambigously' the representation modalities for a single URL.  It seems 
this is the exact purpose they were set out to serve.  The only situation 
I could think of is in trying to resolve the defining ontology of a URI, 
but if you first attempt to dereference it as RDF content (with 
application/rdf+xml,text/rdf+n3 in the accept header), the resulting set 
of triples should include a rdfs:isDefinedBy statement associating the URI
with it's defining ontology (if such an ontology exists).
