This story, from the Wall Street Journal Online's Davos World Economic Forum blog, seems like one of them:
Mircosoft Corp. is developing on an online payment system that will be cheaper than credit card transactions, making it possible for companies to charge small fees for Web-based content and services they now offer for free...
Mr. Gates described a system that would undercut credit card fees, making it profitable for an online newspaper to charge small fees for an individual article, for example. “If you want to charge somebody $0.10 or $1 a month, that will just be a click … you won’t have to manage some funny thing or pay some big credit charge, where half of it goes to the clearing,” Mr. Gates said.
I have seen the future.
