Pretty neat.  There are two problems that still really need to be
addressed.  The first is that you need to manage a transition.  It must
be clearly visible to the user when PwdHash is used and when it is not. 
Otherwise someone just phishes the original password and that's the ball
game.

Second, PwdHash still relies on the underlying security of the user's
computer.  I don't know about you but that is a goal I would like to
address.  I want a means to have a secure opaque channel of
communication between the server and the smart card.  That's what I'm
looking for from the IETF.
