Carsten Agger (from Denmark)
Baobáxia is a community-built project to connect about 200 Brazilian quilombos to assist the interchange and preservation of traditional, community-built culture. A special challenge is found in the fact that many of these communities are located in remote areas with no access to the Internet. It is therefore imperative to be able to synchronize multimedia data offline. Technically, the system uses git-annex to solve the challenging problem of offline distribution - but the really important part of the process is the community effort involved. For more information, here's audio of a talk I gave in Spanish in Rio de Janeiro in July 2015: https://www.youtube.com/watch?v=7Yn5JWV5u9Y
I would also be able to talk about the state of free software in Denmark. I currently work for a free-software-only company here.
