to implement this, one could improve qx.event.handler.Touch to not only track the first touch by id, but instead track all current touches by id eg by using a map or an array as value for __trackId.
This is a bigger effort though, as each touch needs to be checked for gestures (tap,swipe,touchhold, etc. ) separatly.
