Subject: [babel] About unicast Hellos

Is anyone working on unicast Hellos?  We'd really need implementation
experience before we can write it down.

Open issues:

  - new TLV or bit in Reserved;
  - what's the exact semantics of interval=0?

(Support for interval=0 is required, since we really do want to be able to
send an occasional unicast Hello while doing link quality over multicast,
especially when simultaneously doing RTT estimation.)
