A git repository is a content-addressable object store where objects go in indexed by the SHA1 of their content, plus a set of named references pointing at specific objects by hash. The on-disk format (loose objects as individual files, packfiles as delta-compressed archives with a separate index, a ref store split between a directory of files and a packed-refs flat file with a locking protocol that breaks on NFS) is an implementation detail. The protocol for synchronising objects and refs between repositories is what actually matters, and since git-the-program is just one implementation of it, you can swap the storage backend without clients noticing.
When it was done, I asked it to write a simple SDL based integration example. The emulator was immediately able to run the Jetpac game without issues, with working sound, and very little CPU usage even on my slow Dell Linux machine (8% usage of a single core, including SDL rendering).
