I support work on optimistic DAD. I would propose it to be taken up by the IPv6 WG. Not as a part of the 2462bis effort but separately.
I would also note that optimistic DAD is useful for anything that expects a fast attachment time or frequent movements, not just MIPv6 but also HIP and MOBIKE.
I believe the reason it was not taken up by the DNA group was not that they did not want it, but rather that it was felt that the expertise resides more in the IPv6 WG.

Nick,
I think optimistic DAD is a very useful (and essential)
tool for mobile nodes in multiaccess links (e.g. WLANs) since it eliminates a major delay component. So I'd support this draft for a std track RFC.
I'm also surprised that this work is not addressed in DNA as I thought it'd be in the heart of the DNA charter. But regardless, it needs to be done if we want MIPv6 to be useful in WLANs.
