+1, thanks a lot, Pascal. Will only get back after Mar 5 to reply,
some other deadline stuff upfront.

I think the correct term in reality is '"professionally' "managed"' networks.

But kidding aside: resource constrained networks are not necessarily so
autonomic that they do not require 'professional' 'management', that
is just lucky coincidence, so the missing discussion if any would 
have to be about constrained devices and the subset of ACP functionality
feasible/useful. I thought i had already some text in the appendix. WIll
check and improve next week.

Cheers

It would be useful to scope the feature that is proposed in this document, whether it is compatible of not with constrained environments, whether it needs adaptations, point on Michael's enrollment draft. It would also be useful to indicate whether the ACP works between L3 bridges, IOW whether ACP operates the same (over IP) regardless of the packet forwarding layer in the data plane;

ANIMA is chartered for "professionally managed" networks, and the reference model says: "At a later stage ANIMA may define a scope for constrained nodes with a reduced ANI [autonomic infrastructure] and well-defined minimal functionality.  They are currently out of scope." So while your point is very valid, it's been considered out of scope so far.
