There's an easy solution. Only communicate among arbitrarily anonymous
accounts, and always use arbitrary subjects.

On a per account basis, every message that is not encrypted to the public pgp key of the address is dropped, too. users use pop3/smtp over a hidden server to download/send messages.

If you want total overkill, you can use Mixmaster nyms with
alt.privacy.anon-server as inbox. Quicksilver is easy to use, and runs
on Linux in Wine.
