Right idea at the wrong time maybe. A large proportion of the US didn't own a PC 15 years ago and some people still thought the internet was a fad, I'm not sure what PC adoption was like in other countries. There are still some problems to be fixed with the general use of digital currencies, but Chaumian digital cash could make a comeback if there were broader digital currency exchanges and people saw value in it. As for why countries might switch to such a currency... probably to get off the US dollar, but I don't know much about that sort of thing. They'd also have greater control over their economy if they could control their own currency's source code. Also, if bitcoins do take off then the last countries to support them will be poorest and might be better off starting their own currency. I think it could end up being like a stock market, where each unit of currency would represent some unit of specific resources.
