I think it's apparent that creating a native exporter for C2,is not just running a few lines of code off over the weekend,and even if it was then you have the extra burden of support and updates for said exporter.
This would take development away from the core program,and there would be a list of topics venting anger at that...
If you respect what Ashley/Scirra have done with C2,maybe respect their word and put some faith in the decisions they have made...
I think concentrating on the IDE is definately the best way for Scirra to go...with hardware manufacturers climbing over themselves to get the fastest,shiniest products to the market,it's just a matter of time to see the performance of HTML 5 increase accross all platforms.
It's a bit like running for a bus,that is coming towards you...
