Maintenance of Mobile IPv6

Hello,

There are a few things that I think are needed for the maintenance of 
protocol Mobile IPv6; most important appear first:

- help with automated portal authentication in WLAN.  Hopping on and
   off from a WiFi hotspot to another, even without moving physically,
   is often obstructed by web portal authentication requiring user
   to type to fill forms; this is not only inconvenient, but in some
   cases it is impossible, like with vehicular networks where the
   driver is forbidden by law to type while behind the wheel.

- bugs in an otherwise reliable Mobile IPv6 implementation of
   a particular equipment manufacturer (HA never deletes a tunnel,
   lifetime: remaining never): should the bugs be corrected or shoudl
   the spec modified to reflect what the implementation actually
   does?  Should protocol workarounds be designed to deal with this
   problem?

- future of the maintenance of the linux open source Mobile IPv6
   implementation: just for my clarification - is it still ok?  Is there
   some project behind it?  Or is it dying?  Currently the email list
   seems silent, and the latest software releases date back to more than
   one year.

- elimination, or reducing the effect, of the necessity of the 'focal
   point' Home Agent: route optimization for the masses and for moving
   networks as deployed in vehicles.

- Mobile IPv6 and IPv6 NAT Traversal;

- IPv6 NAT in a moving network;

- bypassing Mobile IPv6 implementation (and use IPv6 NATting) in cases
   of particular applications, based on destination IPv6 address and
   IPv6-only-when-reversed FQDN name.

- the use of ULAs combined with Global addresses, with Mobile IPv6
   (e.g. ULA HoA but GUA CoA, or reverse).

What do you think?
