I guess I didn't understand what you want to achieve. If it was simulating the game of air hockey you really can't avoid doing  a realistic collision between pucks. But if it is simply moving a lot of objects around the screen, then maybe the interaction between them would be irrelevant and you would ignore collisions altogether, just collisions with walls. 

See for example "Kaleidoscope Deluxe" in the User Samples (Rev On Line).
Go to the third card (Click box in the lower left hand corner until you arrive at "Bouncing Balls.") And set the velocity to the max.
