I'm a coder at a big media company.
I would die to find a gaggle of people who want to work with me on a simple CMS on top of Git.

As paleolithic as it sounds, I think a CMS build on flat files would be a lot easier to manage than a CMS built on a relational data store.
If you don't need accounts and personalization, or can just do that all client side, you could simply load balance across micro AWS instances pulling from the git repo and stick everything behind Cloudfront -- all for a few quarters an hour.
Nevertheless I think the concept has potential if done right (and with Github or Dropbox).
This should be done.
