that's the point , you cant keep up with the latest flash version = fail . You cant get good performances = fail , you cant run it on old browsers that dont have flash = fail .
Nobody needs that. This has already been done , all the projects have failed. If i had skills i would not waste my time trying to fit a triangle in a star , i would develop tools to make perfect fitting stars. That's what people want.
There's no need to keep up with the latest flash version. If you can render 90% of the legacy content out there (ads, animations, simple games) it's already good enough. You can always fall back on the real Flash player if you need to play a fancy game.
let me run the top 5 facebook games ( made in flash ) and we'll see about the 90% content people can actually use with that!!!
I say that's a stupid project, already been done but nobody's using it, or even care, because it doesnt work !
Interestingly this has been my opinion of all the projects that attempt to create a bridge between native mobile APIS and javascript like phonegap and trigger.io. Don't get me know, they've been noble useful effects, but a lot of that effort should have going into projects like WebKit and Firefox to bring those native APIs to the browsers themselves.
