Body:
We currently believe that the Working Group Last Call for the MOBIKE
protocol document will start in September, and we may be ready to ask
for IETF Last Call in September as well (although the latter may slip
to October, depending on the results of the Working Group Last Call).
All of these steps will take place on the open mailing list.

Ability to co-exist with NAT Traversal is one of the design goals of
the MOBIKE protocol. This aspect has taken a lot of our cycles in the
working group, but we believe that the current design satisfies the
goals. For instance, a client behind a NAT can use MOBIKE. There are
some limitations in special cases, however, but the group's
understanding has been that we can cover all the scenarios that come up
in typical current VPN usage.
