But they don't. Bad guys routinely control zombie farms of 100,000
machines or more. People I know who run a blacklist of spam sending
zombies tell me they often see a million new zombies a day.
This is the same reason that hashcash can't work on today's Internet
-- the good guys have vastly less computational firepower than the bad
guys.
I also have my doubts about other issues, but this one is the killer.
R's,
