Have you looked into Haxe and OpenFL? Or maybe read the article?

The vast majority of the Flash API is available and cross-platform communication is possible through web sockets. Take a look at https://www.youtube.com/watch?... for a nice demo of one such project.

You can already create native iOS and OS X apps using OpenFL, along with Android, Windows, Linux, Flash and HTML5. There's nothing to stop you selling these apps through the various stores.

There are projects underway to create a common API which targets Stage3D, OpenGL and WebGL, but with a bit of work you can do 3D already. Whilst nobody to my knowledge is working on a port of Starling at present, there are great ports of Flixel and FlashPunk already, along with a range of alternative game engines.

Read the article. You're commenting on something completely unrelated. This isn't about creating an insecure alternative to the Flash plugin.

Or as a way of targeting a range of different platforms using a familiar and proven API without needing to learn a different language or worry about understanding the low-level architecture for each platform. By producing a native application for each platform, which targets the hardware directly, it also maximises performance without the overhead of an interpreter or renderer.
