HA reliability can be accomplished by hardware redundancy or by protocol
work.
  do we have a consensus that protocol work is needed at this present time?

MK>>I believe that this protocol work is important and should be
investigated more by the MIPv6 WG. A protocol like this will be needed when
MIPv6 is deployed.
