 Replying to [comment:14 filosofo]:
 > What is the current use case in which you're posting binary data via
 XHR?

 Uploading images (or any other media file) is the obvious target.  Also,
 any generalized API like the one proposed will not be limited to just XHR
 use.

 True, I should have been more specific, I was thinking of per method
 versions.

 >  * Standardization: I don't have to worry about any other Ajax
 functionality or libraries: I just check for the JS methods and call them
 if available.
 >  * Consistent Response Handling: Responses can be only one of the
 following:
 >    * Syntactically invalid response (this includes blank responses)
 >    * Successful response
 >    * Error response

 I don't see that any of these reasons require an RPC approach.
