For corners I'd have the player strike it with his foot. For throws in, I'd have a player quickly throw it to a player nearby who could then strike it with his foot. (I'm trying to come up with a name for this - all I have so far is "foot-throw" and I'm not really feeling it.) I have an inkling that the ball would move much faster into the opposition area catching them by surprise. The pace on the ball would allow for the slightest of touches to divert the ball past the defenders and into the goal. That's my hunch anyway. I guess we'll never find out.
