In forums that look like Twitter feeds or Facebook pages, sales teams can share leads and information about clients (some of it gleaned from profiles on public networks), ask for and get speedy approval of discounts and slap one another virtually ontheback for clinching a deal.
Sensors at the midway point of the table detect the angle, speed, and trajectory of the not-exactly-oncoming puck, and instructs the mechanism how and where to fire the disc -- you slap it back, and the same sequence happens on your compadre's end.
