I'm in turn not sure what you mean by that but I think yes: its about
mapping expected mime types to methods for the creations of object
representations in these types. Example:

The request
   GET /api/rest/package/foo HTTP/1.1 \n Accept: application/json \n
Host: ckan.net
would look up g.representation_registry[('application/json', Package)]
be returned a function like: to_json(obj, mime_type)
and then return the output generated by this.

... In which we would get to implement lookup, error handling and
authorization a third time. (In the current implementation breaking
support for groups etc. btw)
