Ya it's currently hard to find.
http://d-cent.org/fsw2011/I need help from people like you actually. What I've done.
1. defined the protocol
2. implmented it in a C++ daemon that
a) talks to other daemons
b) serves the content managers (frontend UIs)
3. written a (crappy) example content manager.
What needs to happen next is step 3 needs to be repeated by other people who know what they are doing. They don't need to understand the details of the protocol, they just need to understand the basic model, which is just message broadcast, distributed agreement, etc.
Email me for more details, will get back to you later tonight.
