  It doesn't really, it was a reference to your implication that EAP-pwd
cannot stand on its own merit, and requires the disparagement of other
work to prop it up. Which I think we can both agree is not the case.

  Anyway, yes I misrepresented MSCHAPv2. It does produce a key. I was
wrong.

  But I still think the statement that MSCHAPv2 is inappropriate for
doing server unauthenticated provisioning mode is valid even with a
secret key output by MSCHAPv2. I hope we can both agree on that too.
