I think Github could create a good nucleating community for federated networking. They could host a giant pod of Github users (could be the next venue following slashdot>kuro5hin>reddit>hn), and they could also create 1 click tooling for Github users to create pod for their own project communities.<p>Would be a good kickstarter for generating sufficient network effect value to use in the first place, evolving the platform software through real world tire kicking, and getting it out to the wider world. And being github, as well as a sufficiently technical userbase, there's already a business model around freemium hosting which could be applied.
