You can still use an account mechanism, but with an intermediary whose business it is to aggregate small amounts as these proposed and clear the total periodically. That's now one account setup for the customer.
Hal: How, though, would the ftp site which wants to know whether I'm "good for" the one cent charge to download PGP do so? Does it have to check with an agent on the net somewhere which will vouch for me? Aren't the communica- tion costs then the same as an online system? Your agent would purchase the service and immediately resell to you. This legal arrangement need not be the same as the communications flows. The service provider is selling to a large trusted customer; they clear transactions once a day, say. The intermediary provides small amounts of credit to the individual customers, who clear with the intermediary when, say, they go over a limit, like $10. What you have here is a liability transfer from a small customer to a larger intermediary. Eric
