   ditto (remailer server should list remailer properties like

   encryption required? etc)

   standardize remailer help system, standard remailer command format
   (but not neccessaily the commands themselves) Sorta like an SGML for
   remailers

   Get/Creating a nice client. At the moment, 100% of the mail in my mailbox 
is encrypted. I wrote a script called "deliver" which encrypts incoming
mail, then pipes it through procmail/slocal. I modified morepgp
and made it a lot more user friendly (and recursive).

Reducing complexity cost:
  All of this could be lowered by creating an easy-to-use
remailer client which is compiled (or perl/tcl interpreted) and 
installed with every unix out there so it becomes ubiquitous. If someone's 
machine doesn't have a client, they can telnet to a machine where one is set 
up (just like gopher, archie, www) by some generous cryptoaltruist.

  The current remailer solution of putting all of the remailer
system complexity on the server side can't make remailers too easy
to use. My Extropians list software attempted to make it easy
to use by allowing commands to be contained in-band with messages
to be posted. It's still too complex for the user who wants 
hot-key style operation.  (which is why I will eventually write a client
for it)

  Once you write a generalized client that can communicate with
standardized remailers, you can easily include digicash/postage
in the system.

>There much more need for improving the ease of use of remailers than
>for paying for them.

   Are you objecting to paying for remailers on a philosophical
grounds (anti-property/money)? No one has proposed paying real money
for remailer use (although that is a future possibility). There
needs to be some way to authenticate remailer users and limit use
in a "free" sense (instead of top-down rationing) The best way to do
this is to use some form of monetary system.

>The less expensive privacy is, the more privacy there will be.
>Privacy has non-linear benefit; the more that people are private, the
>better any individual's privacy actually is.

   Every standard is enhanced by more people using it. However, this
alone can't be a justification for making services into public goods
which are free to everyone.

   If the Detweilers of the world take advantage of totally free
remailers, they could end up limiting the privacy for all. The same
"free" philosophy has killed many a porno/music/book site (or
created absolutely long user queues reminiscent of food lines in
the xUSSR) Spamming/Spoofing attacks on remailers must be dealt with.

   The situation is not helped by either-or logic. We need both ease-of-use
and some notion of postage.
