(Removed the WHATWG list (cross-posting is such a pain and XMLHttpRequest  
is mostly developed here) and renamed the subject.)

Okay. I guess we can all add support for it and see who screams :-)

I can certainly add this to XMLHttpRequest Level 2 and have been wanting  
to do that since forever. As you might have seen notes to that effect are  
in the specification. send() can be overloaded as per usual. Currently the  
proposal for the response member is responseBody which nicely maps to HTTP  
entity body.

I'm currently writing a new version of DOM Core, but if the above is  
sufficient detail I would encourage everyone to implement it as if it was  
in the specification. I can update it later.
