My burning man camp, http://thephage.org/, recognized the underlying oligarchy in our own organization and decided to make it open and explicit by identify leaders through proxy voting (https://github.com/ThePhage/phage-proxy) on a few different axes: who each individual thought was best at conflict resolution, who we would each go to for life advice, etc.
The end result was remarkably high-confidence, transparent, and harmonious. I expect proxy voting will have a far more significant role in the future.
