So, it's a git server with an interesting storage layer? Don't get me wrong, that part sounds like it might have been a ton of work to implement, but I think the web UI (pull requests, etc) is a lot of what Github has won on historically.
Basically I don't feel qualified to judge the product itself, but I think positioning it against Github, while popular given the recent hard times, isn't quite correct.
Having no web UI, at least even a rudimentary one is kinda a bummer though.
