<slightly off, as this belongs in an RFC listserv>
hash cash is an idea for forcing people to spend CPU cycles to break a
code before they are allowed to send you a message.  Depending on what
the user sets their hash key length to, they can make a sender of a
message take varying amounts of time to break the key.  For individuals,
this might mean that it takes you 1 second or so longer to send a
message; for spammers, 1 second * lots of people = too much time and
effort.  Which reduces the amount of spam.  Has anyone thought about
making this an RFC that extends the various mail protocols?
