Fun project to hack on, but strikes me as kind of pointless beyond the experience/academic value of making it. There are already a number of read-only FUSE-git bridges, and we already have production-ready FTP daemons galore if that's the protocol you prefer. If you don't like the existing FUSE-git bridges make one of those instead. It's more composable; you could also point apache at the read-only FUSE mount for example. You're unnecessarily tightly-coupling libgit2 and the FTP protocol, and probably creating a bunch of bugs (potentially dangerous RCE ones being a network service) in the process.
