Great idea! I wonder why you aren't using github (or bitbucket, etc) for hosting the project. I personally think that early projects can benefit from tools like that, since people can follow the progress (issues, bugfixes, etc) and access the code without cloning the repo.

It actually is on GitHub[0]. I'm not sure why it wasn't mentioned in the mailing list.
