Good, because that's not what I said.
I expect peers to send full cert chains to a small number of common
roots. There's no reason this can't be made to scale, and since
it's the only thing that works at all now, there's every reason to
expect that it's what we'll continue to be using in the future.

As you say, I think that those systems are doomed to failure. Even if
I didn't it's not at all clear to me that the number of cross-linking
certificates is going to be anywhere near large enough to require
them to be fetched via DNS.
