Yes, work is in progress in the branch

/nmap-exp/david/nmap-ipv6

I haven't worked on this for a while, but there are good primitives for
raw packet sending and receiving. Also IPv6 traceroute works (but so far
only interprets responses from the target itself, not TTL exceeded
responses).

./nmap -6 -n -Pn -sn --traceroute ipv6.google.com

I should say that it works "up to interface difficulties." I got stalled
on this work because I had trouble in matching up interfaces to
destinations. I think that libdnet doesn't provide enough information.
You can see how the IPv6 interfaces are matched up with --iflist. If you
are interested I can think back to recall what the problem was exactly
and what should be done to fix it.
