The problem with OPTIONS is it doesn't describe anything about the data the resource returns. I really wish there was a DESCRIBE verb that would return a structure of what is expected to be received/sent. Then microformats could spring up around datatypes returned by DESCRIBE. This is of course very XML. Edit: This would also allow for automatic discovery of new APIs.
