What about mimicking the Qt Project - Nokia relationship?
Nokia keeps their own git repositories for internal development, then
automatically push to/pull from qt.gitorious.org
Closed development is kept closed by developing closed stuff in
separate, non-published repositories (there are very few of these now)
All code is contributed through gerrit, i. e. git + two reviews before
it is merged into the official branch
All code contributions must include autotests. Even after reviewer
approval, it still must pass continuous integration autoapproval: it
must build and not break anything.
It's all explained here:
(of course git helps a lot with that workflow: forking and merging are
very lightweight and smart compared to Subversion)
