+## Search across every public git repository
+
+The [git](http://www.git-scm.com/) version control system has been
+rapidly gaining in popularity both in the world of free software at
+large as well as at here at SIPB. One of the properties of git is
+that every object, whether it's a specific version of a file or a
+changeset to a project's source code, has a unique identifying hash
+(e.g., "8c5fa44b1a4902ba1f84a71df20bfe4f21867a7c"). Given one of these
+hashes, it should be possible to identify which project it came from
+and what it refers to.
+
+The "easy" way to do this is to create a massive single git repository
+with references to every public git repository we can find, but that
+probably causes performance problems, so you may need to be cleverer
+about how data is stored and expose a different interface. You'll
+also need to figure out a way to find all public git repositories.
