I agree. I do believe there is actually quite a lot of work in progress
in this area, and the matter will not be forgotten. The primary driver
appears to be faster movements, which makes it necessary to have better
information distribution from the link layer to higher layers. When such
mechanisms are available, they can be used for various other purposes
as well.

Note that much of this work happens outside the IETF (e.g. 802.21)
or at least outside the EAP WG.

Well, we do have the problem definition document... it has also been
sent as input to the IEEE efforts, for instance.

It would probably be useful to think about these issues also in the
context of PANA. Or does PANA assume link layer under it provides
assistance? But at least some of the limited discovery & selection
functions in the current PANA base protocol are on the IP layer, so
maybe more extensive mechanisms would go there as well. Has there been
any thoughts on where link layer hints fit in the PANA model, for
instance?
