Pax and .fi remailers

Upon more thought, I don't see a really good way to use the PAX
remailer in conjunction with our remailers based on the scripts of
Eric Hughes.  The PAX remailer can only be used to send messages to
those who have "registered" with the remailer to receive an anonymous
ID there.  So, for PAX to work with our remailers we would have to
register.  For example, my remailer at hal@alumni.caltech.edu would
have to register with PAX and receive an anonymous ID, like
"anon.100@pax.tpa.com.au".

Then, to use a two-hop remailer consisting of first PAX and then mine,
you would prepare a message as usual for my remailer:

====================
::
Request-Remailing-To: dest

This is a message for two-hop anonymous remailing.
====================

Perhaps you would encrypt this using my remailer's public key, getting:

====================
::
Encrypted: PGP

-----BEGIN PGP MESSAGE-----
Version: 2.1

-----END PGP MESSAGE-----
====================

You would then send this to anon.100@pax.tpa.com.au.  (NOTE: Don't
try this - I haven't yet gotten an anonymous ID at PAX.)  PAX
would forward it to my remailer, unchanged, which would then decrypt
it and send it onward.  Oh, yes, PAX would also strip the .sig,
which is perhaps why you'd want to do this.

But for this to work, I have to publically announce that my remailer,
hal@alumni.caltech.edu, can be reached at PAX "anonymous" address
anon.100@pax.tpa.com.au.  This seems a little strange, as the PAX
address is then no longer anonymous.  I have to tell everybody what
the address is in order for it to be useful.

So, the PAX remailer doesn't really add much anonymity, but it does
excise your .sig.  It's not clear that it's worth it just for that.

On a more positive note, the other remailer, in Finland, is much more
promising for our purposes.  It has a remailing capability similar
to ours.  You could send mail to: hal%alumni.caltech.edu@anon.penet.fi,
and it would forward the mail to hal@alumni.caltech.edu.  This is
similar functionality to a non-encrypting form of the remailers we
are operating, and so it can help confuse things.

Also, this remailer could be used in a chain of our remailers by
using an address of the proper form.  For example, mail sent to
the Rebma remailer, then to Finland, then to the Rosebud remailer, could be
done by putting, at the front of your message:

::
Request-Remailing-To: elee7h5%rosebud.ee.uh.edu@anon.penet.fi

::
Request-Remailing-To: <dest>

Then a blank line, then your message itself.  Mail it to remailer@rebma.mn.org.
I haven't tried this but it should work, theoretically.

You don't have to tell anyone that your remailer is behind the anon.100
address.  You could just (anonymously, of course) announce that a
remailer is running, and can be reached by sending message to the
anon.100 address.  This way, no-one but the admins at pax can know
where the remailer itself lives.  This could be useful in case 
remailers are banned.
