In my opinion, I don't think an international governing body will work, or at least wont last, unless the powers-that-be earn from it or it serves their interest.
Money is the key to paintball. And, personally, I think that's a good thing. If the key players have their earning potential curtailed, they will move on.
It's no co-incidence that the real powers in this sport are all millionaires. And it's no co-incidnce that it is these very people that have pulled paintball out of the doldrums and into the 21st century. The more they can earn, the more paintball will advance. Limit them at your peril.
Right, time to take cover.
