Also of interest is http://crate.io/

What I've personally been looking for is an easy to setup caching proxy for PyPI. Something that is pip-compatible and serves files if it has them but will also fetch and then store packages if it doesn't. That way you could build up a collection of 3rd party packages over time, without having to explicitly manage it.

It probably wouldn't be hard to roll my own with a reverse proxy but it never gets moved to the front burner.
