filesharing - freedom of files

original filesharing:

Napster - mp3 only, centralized

The original and the start of the revolution.
Today extendable with tools like Napigator and OpenNap, and a huge amount of clones on client- and serverside.
Best.

CuteMX - all kind of data - grouped, centralized

The best 'non-specified' file sharing program, which means its not only for mp3s. Ergonomic, fast and innovative. But maybe soon with fees, have a look at the survey page...

iMesh - all kind of data - grouped, centralized

Another 'non-specified' file sharing tool, but not so easy and fast as CuteMX.

innovative, de-centralized filesharing:

Gnutella - all kind of data - unsorted, de-centralized

Most common used de-centralized file sharing program. But having its problems, so protocol und clients are under development again. Watch out for the new and try some Gnutella-Clones for some improvements now.

Mojo Nation - all kind of data - unsorted, de-centralized

Innovative idea, a file sharing system with micropayment, in ftp-words 'ratio'. So you must upload something, to able to download some other things... Check!

Freenet - all kind of data - unsorted - not searchable, de-centralized, anonymous

The most radical project, they want to 'rewiring the internet' with new URIs and a anonymous and load-balancing protocol for storing the data. In the early alpha days, mostly command line based. But very exciting.
