Wait a minute. I can see how one needn't be a bank to convert ecash into pcash, but going the other way requires that the cash be transferrable in ways that Digicash isn't.
If I withdraw ecash from the bank, it's marked so I'm the one who's identified if it's double-spent. If I give the cash to someone else (different from paying it to them, which requires they have an account) they're free to double-spend with (relative) impugnity.
Present day Ecash is bases on online clearing. I does not encode any user idendifiying information into the coin. You are thinking of offline Ecash. Besides, wherer users get the Ecash from, be it by putting money into their account at MT or buying it from you doesn't matter. They still need an account with MT. -- Lucky Green <mailto:shamrock@netcom.com> PGP encrypted mail preferred.
