I've done some experiments with Stage3D accelerated Flex components, derived from MadComponents classes.
http://madskool.wordpress.com/2013/01/21/madcomponents3d-part5-stage3d-accelerated-flex/ It is my intention to port MadComponents to AS"next". I propose that these ported MadComponents/MC3D classes might form the basis of a new Flex mobile framework that utilises hardware GPU rendering. I'm aware that Thibault Imbert has proposed that a new Flex framework should be based on Starling and Feathers. But I believe that the MC3D approach is better suited to the next Flex mobile framework. MadComponents is a fully fledged framework, not just a UI framework. It allows for versatile styling of components (without having to design texture skins), server communication, and memory management. However, until we know more about AS"next", which framework approach to choose is mostly speculation. So I'd like the members of this group to read my blog post, and let me know what they think.
