OK. So DNSSEC is off the table. At least for now.

At least with Chris's scenario, we can assume that there's an
"administrative domain" that includes a "hub" and some "spokes". This
"hub" has information about the addresses protected by each of the
"spokes", so it makes sense that it will do the "introductions". (BTW: all
the terms in quotes will need a proper definition in the draft).
Alternatively, the "introductions" can be done by yet another node that's
dedicated to these introductions.

So the administrator of this administrative domain may not need to
configure a lot of tunnels, but he or she still needs to configure all of
the encryption domain of all the spokes on the introduces, but at least
that's only one place.

What is a "crypto contract"?

Also, my company calls the addresses protected by a particular IPsec node
an "encryption domain". Can we use this term, or is it too vendor-specific?
