Like the mint uses Alice's public key to sign ecash such that only Alice's private key holder can redeem?
I don't know where I'm going with this, as you can't really use it as currency at that point.
Alice would essentially have an "account" with the mint, who knows how much money Alice has (but doesn't know who Alice is).
Alice's funds are safe from theft*; she could store them in a Google doc or publish them on Twitter.
*Yes we're always assuming trust in the mint
Is this different from just having an encrypted wallet?
Anyone have any other ideas?
