Luckily, I e-mailed Henning and met him today (with Se Gi and Andy) to get an idea of how to come to grips with the situation and proceed further with the project.
It looks like:
- We will release a version that has the basic features, but working.
I think this can be released as source code with configure/make/make install, as well as installation binaries.
- In parallel, we will draft guidelines for future versions and see how to make 7DS more modular so that it is "future-compatible". Things like the community extensions and file syncronization will be part of the next release.
One great wiki I've heard a lot about is DokuWiki...
