I've been tweeting with them back and forth.

Good, then maybe you can explain what they are planning to do. The tech-wow-yippee explanation of their goal is so vague that I have no idea what kind of service/application/nexus they are putting together or how it will help anyone. It is open source though, and involves some kind of software collaboration to produce something web-based or did I misinterpret that?
