I can second this; the Hubzilla platform brings about an immense amount of promise. It's not so much a traditional CMS as it is an infusion of user-centric features and functions. Functionally speaking, you could describe it as a hybrid between forums, cloud storage, publishing, and social networking. It is particularly good for building community websites, but works just as well for single-user purposes. As a whole, the system works tremendously well, and is relatively easy to theme.

The Diaspora community has really picked up a lot of steam over the course of the past two years since becoming a community project. There have been a number of new features added, code cleanups, and usability improvements that have really brought the project a long way from where things used to be. The next major release is on track to include an XMPP component to provide for decentralized instant messaging in the browser. Some other interesting developments going on concern improving federation and moving all of Diaspora's built-in federation calls into a library, moving the interface completely over to one unified framework, improving the usability and UX of Diaspora, and bringing an API for third-party clients to the table. There's actually a lot going on between the handful of projects working on decentralized server-to-server communication. I'd like to think that everyone has a different piece of the puzzle in terms of getting things to work, and it would be nice to think that someday we might be able to put enough pieces together to federate with people on a number of different platforms using the same communication protocols.

Let's say hypothetically, the situation of IP law gets far worse in the future, and software companies find a way to successfully use "Intellectual Property" and the legal system to shut down Free Software projects. To make it interesting, let's assume these entities start shutting down Free Software projects left and right. Assuming that things get that bad, what would happen to Free Software as a whole, and what could the Free Software ecosystem do in order to protect itself from malicious litigation?
