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.
