To say the same thing in different words, the spammer's unattended computer costs 0.0016cents per second, the non spammer's computer is worth about 0.5cents per second, because there is an impatient user sitting there waiting for the mail to complete. Thus the non spammer's computer time costs approximately four hundred times as much as the spammer's computer time.
From this, I conclude that hashcash is not economically viable. We have to use a form of cash that is similarly valuable for spammers and non spammers.
