Hah, I recently had to setup a cronjob that rsync's my org-mode files to iCloud. (iCloud didn't work with symlinks, but I needed to somehow sync my org-mode files to my phone.) Anyway, my org directory happens to be a git repo, and I rsync the whole repo including .git, so that's technically something you can do. :)
These comments are like that famous one where dropbox was announced on HN and someone replied to it with an rsync script “that is essentially the same”.
