What I would want is to GET http://example.com/item/448828 with an Accept header of ‘application/s-expression,application/json;q=0.1’ instead of retrieving the HTML representation of the resource. HTTP is the API.

I also want http://example.com/application/with/path?and=parameters and http://example.com/application to return Link headers with rel=canonical appropriately.

I’d also like world peace.
