Several successful prediction markets already exist, such as Hedgestreet, NewsFutures, the Iowa Electronic Markets, Hollywood Stock Exchange, and Inkling Markets. A spinoff of DARPA's Policy Analysis Market, prediction markets might be to markets what open source was to software.

Interesting idea, but will it work? "Grub provides a free for download, distributed crawling client, which is used to create an infrastructure (database + volunteers) that will eventually provide URL update status information for nearly every web page on the Internet. Grub's distributed crawler network will enable websites, content providers, and individuals to notify others that changes have occurred in their content, all in real time"
