Away3D 4.0 has been released which provides integration with Starling and development with Stage3D.
Rob Bateman and the open source team also inaugurated the Away Foundation. The foundation would be supported by company sponsorship of which Adobe is a major funding partner. (I mean why not? The Away3D community has been working on this this API for 5 years now.) This would permit the development of 3D Flash enabled applications without any licensing costs, or fees.
