i may have misunderstood -- it was some time ago when this topic went
through the rounds :) 

i lack the security background to be able to evaluate the risks that
are involved in rewriting the keys between clients and auth server (an
obvious one is that the mediator will have access to the client's
security keys no?), so back to square one then. :)
