This gathering can be of interest IMO for the free software community, as a self-organizing movement.
The gathering is a general one, has a long history and, I believe, can particularly touch intellectual property subject. It's happening on 13-21 of December. See Wikipedia article and offical site for the current 17th gathering.
On a side note, during the last weeks I returned to Lokalize development: fixed few bugs reported via bugs.kde.org, did few optimizations. I hope you'll like a more polished Lokalize in KDE 4.6 (sorry, the wishes that require new messages will have to wait until KDE 4.7...).
