You can at the very least send each other a zip file containing the .git directory. When you extract that directory into a separate directory, you can add it as a remote and fetch/pull from it (because that's the entire repository right there).

What I usually do is I copy the .git to another name before running zip, so it doesn't extract as .git :)

This is also one of the reasons you shouldn't commit binaries, especially large ones.
