That is where we are headed for sure - our version control allows very granular addressing of content (i.e. an equation or figure). We haven't quite got to the hashing stage yet, because we aren't quite sure what all fits in the content, is the author, date, license also hashed in there? Also right now the way we store our content is still evolving pretty fast as it is more than just a text file etc. that we are storing.

Would love other pointers/thoughts if you have them.

I think this is a really powerful feature for sure.
