Right. And gpg messages are also independently encrypted, although subject isn't scrubbed by default, and some routing information leaks by default (although eg Mixmasters exist as one approach for mitigating the latter to a certain extent. All system will need to have some routing information. Come to think of it, gpg+usenet might be "better" example of "old tech" secure messaging). Ed: i suppose the question.becomes if new systems rely on tls to help obscure meta-data or not; like what mail+gpg does.
