P2P Foundation ning social website

Hardware/Software platforms
Ning
Ning is a ready-to-go professionally run (not open-source) site that provides the tools to quickly set up a fully-functional customizable social web site. It might be a good interim solution for communities who just want a quick alternative to the big sites.
Noserub
Noserub is an open-source social web site that can be set up on a single PC (configured as a server) or on a server. It aggregates user activity from any other Noserub sites or popular big social web sites that the user has an account on. Besides being convenient as an aggregator, it has a big privacy advantage in that the user has potentially much more control over his data (profile, messages, friend connections).
A demonstration (and practically useful) implementation of Noserub is Identoo. You can open an account there to test it's features.
A drawback is that Noserub doesn't yet have built-in groups, but they are in the works for future release. Noserub only has a handful of part-time developers, so progress can be slow.
RetroShare is an open-source P2P network with a strong emphasis on privacy. It's actually closer to F2F (Friend-to-Friend), meant to be very private. Development is more active and it is more socially oriented than the P2P eMule file sharing network.
Open-source file-sharing
We are not really interested in file sharing per se, but the file sharing community has led the way technically with P2P and privacy solutions, so we be able to borrow some techniques. Here is a list of noteworthy examples:
Wuala
Wuala is not open-source, but has an advanced and professional-quality partly-P2P file storage system. It has some nice privacy and social features.
Portable apps
Portable Apps is an open-source solution which allows a user to take not only their data, but their applications with them when they travel on a USB stick. This has implications for P2P hospitality. Besides the general convenience for travelers, our proposed P2P trust network would probably have a private identity key. You could take not only the key, but the P2P trust network software itself on the road with you, making it easier to use from any PC.
Lupo PenSuite is another portability solution which has a long list of portable apps.
