I think the problem is less about how well known the sport is, I mean how many people do you know who go curling at the weekend? I think the bigger concern on the part of the Olympic committie would be damaging the reputation of the Olympics. They see the word paintball on a piece of paper and nothing else, decision made. Even if paintball met all the criteria I think misconceptions about the sport would be the end barrier.....best hope would be for an event organiser to invite representatives to a tournament, NPPL, and build relations from there.
