I've been asked to be a reviewer for this.  My most profound question here is around the choice to make the identity assertion by the OP to the RP out of band.  This is a really significant choice as it puts a huge design issue in the hands of the implementer, that the RP has to provide an HTTP entrypoint which implicitly has some form of RPC with the SASL enabled server to communicate the identity authenticated for a session.  Why was this choice made in favor of having the return form the OP presented in-band as a SASL client message?  

It seems like the choice is to minimize the impact on the client so that a browser user agent can be used for the client interaction with the OP.

Thanks,
