The obvious problem with direct democracy is organization AKA beaurocracy. The simplest solution is to reduce the number of people until organization becomes managable without excessive beaurocracy. This also has the positive effects of reducing the size of each camp and decentralizing the movement. I read in "The Tipping Point" that the largest group in which ever member can have a personal relationship with every other member is about 100-200. I believe that personal relationships are very important for cooperation and therefore I submit that each occupy camp should house a maximum of around 100-200 permanent full time members, and should the camp become larger than that it should divide iteself into two new colonies, thus occupying another location.
