yeah I think we can definitely invite Yoann into one of the next meetings 
so he can present, or if we are meeting at IETF, maybe he might be able to 
attend..

It was partially intentional, partially oversight on my part.

The intentional part was I wanted him to try to do more of "research" 
(since it was his final project in the university), and approach it 
from a more abstract point of view than efficient-nd does - he did look at 
multicast in general, not just ND, so I did not want to bias him, and did 
not emphasize efficient-nd.

But efficient-nd should have been acknowledged as being the trigger for 
all of the work, and that's the oversight that we did not include the 
reference into the text (I was in a rush for a vacation, and I came back 
already after the submission deadline).

Yoann's final thesis is mostly finished, but I think there is 
plenty of further research that can be done - there are a couple more 
points that I think are worth exploring further:

1) Would be interesting to match the network behavioral model that Yoann 
has derived, with the other networks. We analyzed a couple of networks and 
distribution of connections was exponential, if we prove this is 
universal, together with everything else, this could make it a pretty 
powerful tool to measure the network size's impact on battery life. If the 
folks on the team have the access to such a data, correlating it with the 
model would be very useful.

2) Digging deeper into the impact of all-hosts multicast traffic going to 
multiple APs, potentially causing the co-channel contention/interference, 
thus blocking the network at large, and how much this can be different
with different designs.

We can discuss this stuff the next time we meet.
