Even though PANA supports PAA-initiated auth, I do not believe this is
applicable in the case where the target network to which the host is not
even attached would be able to trigger authentication.
So while the PAA-initiated auth makes sense in the regular PANA use case, I
don't see this as being valid in the scenario described in the pre-auth I-D.

So I would recommend dropping this scenario from the I-D.
