Is the recommendation in section 5.9 that the original ike initiator
can change on an IKE SA rekey consistent with mobike?  Does that mean
that in the case of mobike, you want to make sure only the original
initiator rekeys in order to avoid changing which side nat works best
with?

I'm not sure I agree with the text in 7.1 that claims the IP address
ID payloads don't impact the traffic selectors.  As far as a direct
implication, it is true.  However you do search the SPD based on the
IP address payload and that does effect traffic selectors.  For
example I don't see how to configure the SPD to allow someone claiming
an Id of 10.0.0.6 to match a policy that doesn't have 10.0.0.6 in one
of the traffic selectors.
