Anyway, McCloud's micropayment comic is up [scottmccloud.com]. It seems to use a system called BitPass [bitpass.com], which is basically an account that you can fund with a credit card or PayPal, and then spend will-nilly all over the internet. Of course, you can't, because McCloud's site is the only place you can spend the money. So your minimum $3 account can buy you 12 views of McCloud's comic, but not much else.
Ignore the signup hurdle. Ignore the lack of purchaseable online content or support for this system just about anywhere. If this is a feasible business model, why wouldn't PayPal just implement it themselves? They could knock these guys out cold with a mere thought -- they could just eliminate the middleman and use their huge established base of sellers and buyers. But they don't because it's not economically feasible for them to put a micropayment system like this in place. The individual cost of transactions is just too high. I give BitPass less than a year before the company closes shop and takes their ball home (likely taking the balance of your BitPass account with them).
