I think a 3rd repository for hordeweb, presentations, and other  
utility stuff (like the git hooks) might make good sense. hordedoc  
could be its own repository also.

Though it's worth pointing out that hordeweb will hopefully stop being  
something under version control once we switch over to hydra.
