Anonymous web hosting
I typed this once but my internet went down, so I lost it. Therefore I will be brief: Use the the Tor network to anonymously host a website, and allow the public to view it through a website that is able to interface with the tor network. This would allow a content provider to be completly annonymouse in there dealings, while being accesible to the general public. Only the site directing users to the tor site is at risk.
