Hi Marc,
Although somewhat off-topic for this list, I would say there's several people out there that aren't at all happy with OpenStack (myself included).
However the requirements for creating an interface for virtualization management can very quickly become overwhelming, as there are so many areas this could expand into.
OpenStack has contributions from a lot of people, and backing from some big names, so you'd be hard pushed to create an interface that covers all use cases.
Bare in mind that some aspects of such a platform, such as the REST API, if done properly, are difficult to achieve with stock Django.
The best way to get like minded contributors is to start work on something yourself, and attract people along the way. Create a prototype or an alpha, learn from the mistakes, and use the experience to not only become a better programmer, but to determine what the goals of your project would be. If you're not busy this weekend, have yourself your very own hackathon :)
Also decide early on what your personal goal is... if you want to ship a product, then focus on getting it done by any and every means necessary, potentially compromising quality for speed. If you want to improve your own skills, then focus on learning and take as long as you need to get the job done right.
As a startup kid, that's my two cents.
