A stable version of Kiwano is now running on our servers. It has been implemented in Python and C++ using twisted networking engine and cgal library for computing Delaunay triangulations.
Documentation and sample code to connect the open API are available at kiwano.li. HybridEarth and Manycraft are the first systems to rely on Kiwano API and hopefully others will follow. If you plan, even remotely, to use the API, please advertise yourself on the mailing list.
This article presented at HPCS’2013, describes the architecture and algorithms of Kiwano.
