It (as usual) all depends fro the hardware support i fear :/

I know  QTouchEvents and the higher level gestures in Qt are supported on osx 
wit their touchpads.
no idea under linux tough (i would guess no, since the multitouch framework 
directly reads from the event device of exactly the touchscreen panel it's in 
the lenovos, that also, support only two input points)
It will migrate to XI2 tough, so should become less hacky.

also, the mac touchpads i think are quite different from the usual synaptic in 
the other laptops, there is some gesture support i think, but dunno how much 
access there is to this stuff.

Aanyways, i think everybody that has any kind of device where qt supports 
qtouchevents should play with them as much as they can, so when the underlying 
stack becomes less a tragedy, those things should start to work for everybody.
