Your reply is filled with sarcasm Brian... that isn't the goal of this thread. This is happening and ideas are being thrown around. I would really appreciate if you keep that kind of stuff out of here... it makes it easier to achieve the goal of this topic.
As for your comment about paint being present, a solution has been found to make sure paint won't be a problem, thereby making the arena accessible to both paintballers and airsofters. I have taken the advice of one of the people who have replied here and checked out those paintballs that have powder in them. Found it, contacted their people, and it's all good.
Money won't be a huge problem.
