I'm working on my own project which has two parts:
A. kernel/generic code (public part)
B. code which works with proprietary protocol etc (private part, available for me and a few authorized persons)
I want repository hosting (maybe github, assembla, ...) which allows working in public and private branches in the same repository.
I don't want two repositories because I'm actively working on both parts and I want to avoid diverged repositories.
Which solution is available for me?
