Subject: * Located and destroyed the weird velocity and rotation transfers. 
 It turned out to be that the Static PhysicsVector.Zero was transferring
 velocities between all non fixed objects.   Not so static after all :(. 
 Finding it was cruel and unusual punishment from the CLR. * Therefore, when
 you run through a pile of prim you won't see things rotate when they're not
 supposed to anymore. * Avatars don't float off either.
