The Webtorrent plugin is a fascinating piece of kit as it allows creators to build new and exciting applications which can rely on distributed torrent technology than the traditional server-client configuration.
Check out my Github page for an example project built with SailsJS, a web framework on top of NodeJS and Express. The application loads with a single allowing users to instantly copy & past a URL to be archived and made avaliable to download using their faviourit torrent client. The archive includes a desktop rendered screenshot and html data dump. The files are also hashed and store in a third file for referencing and integrity purposes.
