Serve bare git repo from a remote server?

Hello, firstly - thanks for the amazing repo.

I understand that in your implementation (and stackdot's), you use `git-upload-pack` and `git-receive-pack` processes to allow the client and server to talk to each other (figure out what packets the other needs, etc.) To my knowledge, this git command accepts a local directory, but what if I host all my bare git repositories on a separate server, like an AWS S3 bucket? Could I stream a remote bare repo to these git commands, that then stream the necessary packets to the client? I don't want to host all my bare git repos on my heroku instance, since the storage is ephemeral and limited. Any guidance would be appreciated!

Start by tracing how the project uses git-upload-pack and git-receive-pack, then determine whether their local repository requirement can be met with a remote bare repository such as an AWS S3 bucket. The issue does not name files, tests, or a concrete completion criterion, so the remote-storage behavior and implementation scope need to be defined first.
