OpenRelay is a p2p (peer to peer) based web hosting solution. OpenRelay is free (as in freedom), which means it is currently licensed under the GNU GPLv3.
The goal of OpenRelay is to decentralize hosting, create an alternative to paid hosts, and to allow anyone (with a few friends) to be able to host a site.
OpenRelay builds upon the BitTorrent Protocol developed by Bram Cohen, as well as other projects like Twitter's Bootstrap, Werzeug, Django, Python-gnupg, PyCrypto, and AutonomoTorrent.
