You can cryptographically hash tags so that third-parties can't read
the contents of the in-headers. For security, a salt should be appended
to the tag name to make dictionary attacks on the tags more difficult.
For their owners' convenience, mail clients will want a mapping of hash
to tag name.

A single RFC2822 message can store the salt and hash-to-tag database. It
could contain a clear subject and directions to the end user not to move
or delete it. This would not, I think, terribly confuse existing mail
clients or their users.
