i am actually eagerly waiting for someone to show the real-deal: actually everything in a github repo, including 'artfiacts', or atleast those artifacts which can't be reconstructed from the repo itself.
maybe they could be encrypted, and you could say "well its everything but the encryption key, which is owned in physical form by the CEO."
theres a lot of power i think to have everything in one place. maybe github could add the notion of private folders? but now thats ACLs... probably pushing the tool way too far.
