I think some may recall World Social Forum, an event that happened in Porto Alegre, Brazil in the beginning of this year.
WSF was a massive event. In it, politics, technology, environment and much more was discussed.
In the techn. aspect it gave an introdution of an event to happen this following month: The International Free Software Forum.
Porto Alegre, So Paulo and a handful of others Brazilian cities are governed by the left (Worker's Party) and they've been trying to insist in a "free and participative" government in all instances possible, in POA's case that includes technology.
So, the FISL will happen from 2-5 in May. It's very likely that the agency which I work (www.hotbits.com.br) will have news about it everyday.
