Any big reason not to have an archive repo, with tars of your archived projects? You still have git for your tars, and thus all your versions. It seems like a fine idea, to me. To archive a project, tar its project directory, copy it in to an archive repo on github, commit and push it, and remove the directory locally. To unarchive a project, pull and untar the project in its own directory. When done, tar it back up into the archive repo, commit, and push.
