Ted,

Juliusz can correct me if he disagrees,
but my understanding of the current status of unicast hellos in Babel is:
1) The community agrees that we want to support them
2) The community hasn't yet come to a consensus on how to encode them,
proposals included a new TLV, a flag in the existing TLV, and a sub-TLV.

I think we were waiting for proponents of each alternative to write code.
I'm hoping to work on that in a couple weeks after our developer conference.

While the Homenet Babel profile could technically be achieved without
unicast hellos, I think they expand our options, and since they are at the
top of the Babel WG's agenda, it's worth waiting for them.

David

I sort of thought that that had happened, but I didn't see a clear conclusion because I got busy on some other stuff right when that discussion seemed to stop.
