I don't remember how I found it, but this it's a killer feature to use S3 to host git repos for archival. I now have 3 copies, it's overkill, but Heroku, bitbucket & S3. Unfuddle also has free private git repos.
The best part is that since it's still just a git repository, once it's local you don't have to bother with jgit at all. I'm going to replace a custom git bundle + tarsnap backup thing I have going with this tonight. Gonna be great.
