CoralCDN is a decentralized, self-organizing, peer-to-peer web-content distribution network. CoralCDN leverages the aggregate bandwidth of volunteers running the software to absorb and dissipate most of the traffic for web sites using the system. In so doing, CoralCDN replicates content in proportion to the content's popularity, regardless of the publisher's resources---in effect democratizing content publication.

One related question is how such information plays a role in pay-per-click advertising, so we decided to run some ourselves to better understand how such systems work.)
