Ideas for a central CMS?

This is interesting, I would like to implement the same thing on a CMS as well. Someone told me about SVN (subversioning) but I don't know if that would entail updating a system. You could create a class that retrieves the updated code from a central server, then parses it, though I'm not sure if this would be the best solution.
