Wild pockets vs Silverlight

I've been trying to port the games to Microsoft Silverlight.
It was then when I discovered how sweet the Wild pockets game engine was and how complicated Silverlight happened to be.
It still needs to overcome the penetration of the Flash plug in but who knows what's going to happen in the future.
