In the context of this discussion, optimizing Mobile IPv6 handover
speed seems to imply that slowness of those is the root cause of that
lack of MIPv6 deployment, which I don' t think is the case. On the
other hand, coupling network access authentication with mobility
management would arguably reduces deployment flexibility and thus harm
rather than help potential MIPv6 deployments.

Thus I am still not sure what the problem is.
