I am involved in the synaptics Xorg driver. I have an experimental Xorg driver utilizing the multi-touch interface. The plan is to map stable gestures to the existing toolkit events, removing the need for programs like syndaemon. > For instance does the X.org driver interpret the data and emit a zoom or > rotate event based on the finger position and movement?

It could be a long implementation process... :( Every journey begins with a step.
