Praxis: a Ruby framework that takes a different approach to creating APIs

RightScale recently unveiled their new Ruby framework. They call it Praxis and it takes a unique approach to building APIs. From the announcement:

With Praxis you create an API by going through the design, review and implementation phases and iterating over them as necessary. Each phase is done independently, and possibly by disjoint sets of people. For example architects could design it, developers implement it and both can review it alongside the customers.
