Now metrics join the game. Currently not part of NHDP, while this
is strongly related to neighborhood. Metrics would be used not only
by OLSR (e.g. distance in DYMO).

Another thought: is it up to NHDP to keep track metrics for the link 
to the 2-hop neighbor? If not, I think there is no problem.

And a remark on the address uniqueness: is anycast permitted? And what 
if a lot of duplicates are in the network, all on different media?
I was present at an event with some ad hoc networking. I saw a lot of
192.168.0.0/24 networks. Luckily, nobody was shot.
