We're coming to similar findings as well. Our prototype (here) spins an 8" wheel at 1300 rpm and spits an orbit ball a good distance with a ton of backspin. The time it takes to spin back up looks short enough to possibly shoot 3 or 4 balls a second. This is with about a 4:1 reduction off of a single CIM motor.

I don't see the need to shoot the ball any further than 10 feet or so, but I may be wrong (it's happened before...).
