You may be interested in this conference. I am on the Board of Computer Professionals for Social Responsibility (CPSR) and will be at the event.
CPSR (Computer Professionals for Social Responsibility) is sponsoring a barcamp-style "unconference" on Technology and Politics on Sunday, December 17 in San Francisco.
The goal is to create stronger coalitions devoted to democratic technology, freedom, social justice, and sustainability.
Sign up on the event wiki.
