The wiki pages are just another Git repo; you can just clone it and get a full copy. Pages simply turn into files containing Markdown markup (teehee).

Not sure about the issues or other things, though.

Issues are accessible via the API: http://develop.github.com/p/issues.html

A git-based wiki? My respect for the GitHub guys continues to grow.

The code behind the Git-based wiki is also open source so you can view and edit your wiki locally via a nice web interface, and build your own tools using the API: http://github.com/github/gollum
