gitolite is pretty fancy but depends on a text based configuration, and it's easy to make your own git-shell which is basically a shell that will allow certain commands, and assign each ssh key to a git-shell with arguments such as a username if you want to bind to a db or something

Well, to be fair, you don’t need gitolite for that. You can just do that with any account and the right .ssh/authorized_keys file. prgmr.com uses/used(?) this for out of band access to VMs for example.
