I've got a storefront in Chicago. What would prevent me from opening up a Mark Twain account and buying and selling ecash on floppies, in person?
You touched on a very important issue: the party converting currency into Ecash does not have to be the Ecash bank. There have been discussions that in the future one should be able to buy Ecash on floppy at the local supermarket, similar to today's prepaid calling cards. I certainly would like to see that happen rather sooner than later.
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. What'd I miss?
