How's this for a formidable task: getting the world to accept and actually pay for a new sport. Zoneball is a kind of circular game of catch that all but eliminates physical contact by restricting players to individual zones; with patents in hand, Stratball Sports, in Marstons Mills, Mass., aims to sell the rules, field design, and balls to institutions as a safe sport for coed groups. So far, some 400 schools have snapped up the $90 to $150 packages.
