Open Source rocks my world and should make everybody happy. It works like this: somebody "invents" something, somewhere, that's really great and tons of people will want to use. Anyone who wants to replicate or work with that invention can do so for free. There is no licensing agreement required. You make your thing work with their thing, and together the collective value of the system increases. Very utopian however, because that vision is a very naive view of the process.
