I understand that argument, and the document is far from finished.
But how can we encourage people (not just IETF people) to provide
the experience? I think we need open source implementations of the
ANI components ASAP.

Again: we need experience, not theory, to clarify this.

Remember though that ANIMA is a *management* mechanism. Certainly
it can manage virtual functions and components, just as easily as
physical devices. I don't see a problem of principle here at all.
The ASAs need the administrative privilege necessary to manage
the virtual components, that's all.
(The ACP itself is a virtual network, using VRF functionality.)

GRASP requires a secure substrate. It doesn't actually *require*
draft-ietf-anima-autonomic-control-plane; that's just the first exemplar
of a secure substrate. GRASP could be deployed tomorrow over any other
sort of secure substrate (or, heretically, with no security at all,
but I don't advocate that outside a hackathon).
Alex, can you propose a simple alternative to the ACP?
