Based on Azureus, Localhost is a program that lets you access a shared, world-wide file system through your web browser. This file system is maintained in a fully decentralized way by all of the computers running Localhost. The program uses BitTorrent technology, and new Distributed Hashtable technology called Kademlia. Every user accesses the system from the same root folder. You can change any folder (including the root folder) by adding files and/or folders to it. When you make changes to a folder, a new version of it is created. This results in each folder in the file system having any number of alternate versions. Each user can view any version of each folder. The default version of a folder displayed to users is the most popular version, where the popularity of a version is determined by the number of users that have chosen to view that version. If you make some changes to a folder, which makes a new version, other users will view that version, and if they are good changes, they will continue to view that version, rather than any other version. Your version will become popular, and it may become the default version of that folder for everybody to see. You can include your name on the description of the version. (But you need to keep the program running on your computer until at least one other person chooses to view your new version. When no-one online is viewing a particular version, it dissapears.)
