I stand corrected.

>b) there is no body in a GET method, and no reason to add one;

Well, my reading of an admittedly somewhat old HTTP spec gives me
       HTTP-message   = Simple-Request           ; HTTP/0.9 messages
                      | Simple-Response
                      | Full-Request             ; HTTP/1.0 messages
                      | Full-Response
       Full-Request   = Request-Line              ; Section 5.1
                        *( General-Header         ; Section 4.3
                        |  Request-Header         ; Section 5.4
                        |  Entity-Header )        ; Section 7.1
                        [ Entity-Body ]           ; Section 7.2
       Simple-Request = "GET" SP Request-URI CRLF

       Request-Line   = Method SP Request-URI SP HTTP-Version CRLF

Which does not seem to me to disallow a GET method from having a body,
except as a "Simple-Request". If the get method is sent as a "Full
Request", it can take a body. Most current servers do not support
this, but if they can support POST, they should be able to support
GET, indeed, we loose very little if we remove the "Simple-Request"
clause from the above.

Also, there is a reason to add one; For certain types of applications,
it makes very good sense to send additional data with a GET, and
unless we allow Entity-Bodies, there is no reliable way of sending
additional information that uses anything other than ASCII. It is, of
course, possible to achieve much the same thing bu overloading the
semantics of POST, but that makes as much sense to me as calling
read(), write().

Hmm. It seems to me that allowing content negotiation for all fields
makes more sense.
