The Hunting of the Snark Project contains a client for downloading and sharing files distributed with the BitTorrent protocol. It is mainly used for exploring the BitTorrent protocol and experimenting with the GNU Compiler for Java (gcj), but it can also be used as a regular BitTorrent client. Snark can also act as a torrent creator, a tiny HTTP server for delivering metainfo.torrent files, and has an integrated tracker for making the sharing of files as easy as possible. When you use the --share option, Snark will automatically create a .torrent file and start a very simple Web server to distribute the metainfo.torrent file and a local tracker that other BitTorrent clients can connect to.
Mnet is a universal file space (a single, global virtual space into which you can put, and from which you can get, files). It comes with a single global namespace so that there is no conflict over filenames. It is also an emergent network, one in which the important features of the network result from the interactions of nodes operated by autonomous people or organizations who do not explicitly coordinate with one another. There are many interesting applications that can be built on top of an emergent network and a universal file space. The first application that has been written for the Mnet project is a file-sharing application which lets you search for and download files of all kinds from the universal file space. Mnet is descendant of Mojo Nation.
