Go to any gathering of open-source developers and someone is bound to tell you that free software isn't free - not free as in "free lunch," anyway. Free as in "free speech."

The documentary film Revolution OS was released Friday on DVD. The film features interviews with Linus Torvalds of Linux fame; Richard Stallman of the GNU/Free software project; Eric Raymond, author of Cathedral and the Bazaar (a treatise on marketing and open source); Rob Malda of hacker discussion and news site Slashdot; Larry Augustin, co-founder of VA Linux Systems; and others.
In the spirit of open source, the DVD was released without CSS, the content scrambling system used on most commercial DVDs.
