The concept of distributed version control makes vendor lockin on a product like GitHub almost a moot point. For instance, see the _why mirror: http://github.c

The concept of distributed version control makes vendor lockin on a product like GitHub almost a moot point. For instance, see the _why mirror: http://github.com/whymirror http://github.com/whymirror - while not the same situation, it is similar. GitHub's issues and wiki pages are not included in your repository, although I know the issues have a very nice API (I'm not sure about the wiki).
