https://xkcd.com/927/

It is evident (now!) that my conception of these conceptions was
different than the homenet starting point. I envisioned lots and lots
of keys interconnecting a multitude of networks, where the design as
stands is oriented towards securing a single domain.

further, I've learned now, dtls would be a better interconnect, and
considering how to do that well might factor in the above standard.

I would still rather like to be able to test key rollover by christmas!
