Box 2d , controllers , in-app

Hi

Some questions :

1 )  Is it possible add box 2d to player and make gravity ? I want make an easy platformer  into the game .  Simon said box2d is in VS5 but not finish yet .

2) Player control in some scenes is only with keyboard . How can I integrate it with left and right shapes in screen and also shooting too ? I want use it for mobile ports

3) Is it possible add in-app purchase feature for markets ?

Thanks

Simon is already busy with the integration of box2D. But it's a HUGE and complicated thing to do. 

Brilliant !!! . I can't waiting .
Thanks so much for your hard works VS team.
