Thanks Jim. Let's see..

cloud-init is not a good place to have private information, as you
anticipated. The fact we have other private information there is no
excuse to introduce an insecure mechanism that is precisely
attempting to improve security.
William already had a better grip on that problem, but there was one
gotcha on his approach that he understandably didn't think of which is
the fact txaws itself is completely insecure to man-in-the-middle
attacks (which is, again, what we're trying to solve) since it doesn't
verify the SSL certificates. The first step towards introducing
security against man-in-the-middle is to fix txaws.
-- I'm not absolutely sure of anything.
