also, my question about whether one loses the downloaded Chaumian bucks if one's hard drive crashes was answered in the affirmative by Levy.
But as I said, if the drive is backed up you don't lose it. It's my understanding this is the case with the current Digicash/Twain bucks. But not necessarily with all implementations. This "lose your money" with digital cash really does seem to get to people. I always point out that when you take $ out of an ATM machine, you don't expect to get it back if you lose it. For those forms of e-money that are irretrevable when lost users are warned not to download huge amounts. Question: will people's worries about losing their e-money lead them to accept a higher degree of tracibility as a tradeoff? Steven
