1) You won't want to pay a dollar in most cases until you've made sure the article is worthwhile, and then it's too easy to claim that it really wasn't worth that and try not to pay your $1.

2) Agree with another commenter here that for the scheme to work it has to be in the pennies region, so that it's worth you taking that non-repudiatable change on something that you have not yet seen. (Prestel in the UK decades ago made this work, BTW.)

3) My previous-but-one startup was a small e-money issuer, and I really tried to get traction in this area but couldn't. Would still like someone else to make it happen!
