Again on the topic of e-currency..

I've been wandering around on the web and reading up about LETS, and other funny nontraditional ways of trade, and found this pretty interesting page, which has a lot of information on various projects.

One of those, which has some interesting ideas, is the epoints. Quite funny how they tackle the issue of "copying" of the notes by using the one time challenge-response scheme - maybe this could be usable in the future as a base for something...
