PORTO ALEGRE, Brazil - Activists at a leftist gathering where Microsoft is 
viewed as a corporate bogeyman urged developing nations Saturday to leap 
into the information age with free open-source software.
In a packed warehouse where tens of thousands are attending the World Social 
Forum, Grateful Dead lyricist John Barlow said poor nations can't solve 
their problems unless they stop paying expensive software licensing fees.
Open source software includes programs that are not controlled by a single 
company. The software can be developed by anyone, with few restrictions. The 
best known such software is the Linux (news - web sites) operating system, 
which can be downloaded free from the Internet.
"Already, Brazil spends more in licensing fees on proprietary software than 
it spends on hunger," said Barlow, co-founder of the Electronic Frontier 
Foundation, a cyberspace civil liberties group.
Barlow said Brazil is trying to wean itself from Microsoft with a campaign 
to persuade Brazilians to shift from costly Windows products to applications 
that run on the Linux operating system.
Microsoft contends open-source software can be more expensive than Windows 
programs when service costs are factored in.
How much people spend on Microsoft products is unclear because the company 
often provides discounts when it senses it may lose business. However, 
competition from open-source software has prompted Microsoft to offer those 
discounts.
Brazil President Luiz Inacio Lula da Silva's administration says the 
open-source policy makes sense for a developing country where a mere 10 
percent of the 182 million people have computers at home, and where the 
debt-laden government is the nation's biggest computer buyer.
China, France, Germany, Japan and South Korea (news - web sites) also are 
pursuing open-source alternatives. In a partial response to the open-source 
threat and to piracy, Microsoft last year launched stripped-down, cheap 
versions of Windows in Indonesia, Malaysia and Thailand. Similar products 
are on the way for India and Russia.
Joining Barlow on Saturday were Brazilian pop superstar Gilberto Gil, who is 
Brazil's minister of culture, and Lawrence Lessig, Stanford University law 
professor and chairman of Creative Commons, a nonprofit organization devoted 
to sharing creative material online.
All the social forum's 800 computers are running on open-source software, 
but the loosely organized event ran into an embarrassing glitch Saturday's 
when two big screens betrayed the fact that the computer was running on 
Windows, with the operating system's toolbar visible at the bottom of the 
screens.
Lessig noticed and the computer was quickly disconnected and replaced with a 
laptop running on open-source software.
