I am working on a social software system for publishing personal data on a distributed basis, Friend2Friend, an authenticated Peer2Peer system. I'm doing it on an altruistic basis, not for profit. It's more work than I can manage alone, so I'm breaking the project down into pieces and hope to be publishing more about them in the next month or so.
I could do with some help on this. Get in touch if you think you might be interested.
