BitTorrent is a tool for copying files from one machine to another. FTP punishes sites for being popular. Since all uploading is done from one place, a popular site needs big iron and big bandwidth. With BitTorrent, clients automatically mirror files they download, making the publisher's burden almost nothing.

The aim of the PicoForge project (previously known as PicoLibre) is to provide a set of high level libre software applications that are well integrated in order to provide a collaborative "forge". It makes it easy to deploy a collaborative work platform for developing software or hosting other collaborative activities. Having started (as PicoLibre) in an educational context, PicoForge is now a quite generic platform, comparable (but sometimes less advanced) to other *-Forge software platforms. It groups several high-level applications like phpGroupware, Sympa, TWiki, Subversion, and CVS.
