Brazil's efforts in this area are well-known. While the general public may just pirate software and movies, government must be more circumspect. The Brazilian government figures it can save $500 per worker by switching to open source, and is thinking of making the switch mandatory.
This has caused big moves in the private sector. Look at the Zope Web site, for instance, and you'll find a grand training tour being undertaken this fall in Brazil by a local company. That's a lot of knowledge, and more on the way.
South Africa, too, is considering switching to open source at a savings of billions of rand.
Software is stuff, and that's what is driving change. But what will really change the world is when the people using that stuff create innovations that they can share with us.
Because in open source, our stuff may be your stuff, but your stuff is also our stuff.
