OK, for those who are interested in, here's the link @ Revolution OS, "a 2001 documentary which traces the history of GNU, Linux, and the open source and free software movements." The interesting fact is the method that Stallman used to create GNU (start form 12:50th minute): "...a large number of separate programs... replace these programs one-by-one...", that substantially is the same - but with some modernization, such as the "opening manager tool" (an hacked package manager) - that i suggested for open sourcing win9x idea.
