How will things like X11 go about > leveraging this functionality? What I have in mind is this: 1. Add support for the MT interface in the trackpad drivers, to the extent they support the information. First out is bcm5974, for which the interface is designed. A patch is prepared, but I will keep it on hold for a little while longer. 2. Add support for the MT protocol in Xorg synaptics and/or a new Xorg multitouch driver. As you might have guessed, I have an experimental driver, utilizing the MT protocol. It uses proper matching techniques to obtain smooth multi-finger actions. My plan is to launch this in user space as soon as there is kernel support.
