Remote Control Ball?

Who knows why dogs love fetch, but they do.  A lot.  My dog goes after the ball like she's going to save the world.  And then she'll do it again.  And again. And again.  As long as you're willing to throw it, she'll go after it with all she's got.

Fetch is a great game, but it's not particularly satisfying on the human side of the equation.  If you don't have a ball gripper, it's even worse, what with saliva and dirt and whatnot.

What I propose is a new form of fetch in which we humans have some form of control over the trajectory of the ball.  It doesn't have to be hi-tech like a remote control ball, but I admit that would be pretty awesome.  I have no idea if this is even possible.  Would you have to use magnets or wind or electricity in some weird never before thought of manner?  You figure it out, brainster.  I'm just telling you what I'd buy as a dog-owner.  Woof.
