i have read 3 book relate to the open source movement just for fun and rebel code and free a in freedom . this documentary tell much the same story a in the book . however and it be kind of neat to meet some of the key player and hear them personally give their observation and viewpoint . it be also neat see them in person because they portray a different image than i sense from the book . they be real people dedicate to a great endeavour . for anyone interested in open source and this documentary be a must see .
