Discovered an interesting bug just a few moments ago when boosting my friends with my monk. If you reach the instance limit for the hour and try to do a Flying Serpent Kick into the instance portal you will be put back in your spot and keep the same speed as if you were flying except you are running and in control of your character! Doesn't run out and you can run on water, you are however pacified. You can still mount up but any change in movement speed will break the effect and you will still be pacified, simply relog to fix.
Enjoy.
