The uTouch gesture stack supports up to 5 touch gestures, and although most of them are either hard to do on a trackpad or are not possible with this driver, I can think of uses for 5 finger tap. Unity uses four finger tap quite effectively I believe.
There is a meaningful limit to this: five fingers on a human hand. It seems more arbitrary to stick the protocol limit at four fingers.
