Ack.

I think I started the discussion with Julien on that point, because of
the following from section 3 in RFC 5014:

                                             Another example is the IKE
   application, which requires a care-of address as its source address
   for the initial security association pair with a Home Agent [RFC3775]
   while the mobile node boots up at the foreign network and wants to do
   the key exchange before a successful home-registration. 

I have no specific problems with the changes proposed by Julien but I
don't like the idea of having a pointer in RFC 3775 leading developers
looking how to use the CoA for IKE implementation with MIPv6 to the
previous block of text. Simply because there are open issues (to say
the least): I am still waiting to be proven otherwise, but got no
response to the last mail of previous thread:

  Archived-At: <http://permalink.gmane.org/gmane.ietf.mip6/7611>

As far as I can tell, the only *working* solution (i.e. *implemented*,
i.e. not just *expected* to work after paper review) is derived from 
draft-sugimoto-mip6-pfkey-migrate-04.txt.

I'll post more on that before the end of July.

Cheers,

a+
