In 2002 I described United Diversity as “a member owned and stakeholder governed network of mutual advantage.” In truth, it was aspirational. At the time, the flexible off-the-shelf legal structures and open source tools needed to make such a network a reality simply didn’t exist. Now they do. Co-ops that combine best practices from the international co-operative movement with best practices from the open source software and hardware communities are now possible. Soon anyone will be able to set up an Open Co-op and invite all their stakeholders to help finance, govern and organise the co-op online.
