All true. But it isn't designed for negotiation as far as I know,
just a request/response.

Agreed, that is a little higher up the food chain. Maybe that is as close
to the user as an ASA will get. I don't really care; I just wanted to
explore the way we might fit our various tools together.

Yes, indeed, and then we could discuss how the radius server gets new
address space when it runs out.

Yes, by defining a full set of relevant objectives.
