As far as I know, Xile is the only person to get KeyGrip working with Paintball 2. But he soon abused this power, and sped up demos of everyone, and the speedhacker threads became so abundant, Xile was trapped in a giant ruby and transported to KnacK's barn where he rests today. Again, that's as far as I know. It's probably 50% rumor, 50% truth.
