NTLMv2

I'm sure you get this request all the time, but I'm wondering if
NTLMv2 proper (not LMv2) is on the roadmap, and if so, if you have any
idea whatsoever approximately when.

If not, and if I wanted to contribute it, is it simply a matter of
implementing the correct behavior as outlined in the davenport spec
(which I understand may not be trivial)? Or are there some blocking
issues?

Thanks in advance,

Matt
