After a first glance at the spec, here are some questions for discussion:

* On which element(s) are these touch events dispatched, especially in 
the case of simultaneous touches on different elements?

* Do elements "capture" touch events, as they do in current WebKit browsers?

* What are the advantages and disadvantages of the TouchList model, 
compared to the one-event-per-touch model in Gecko?  (See the Landscape 
wiki for some background and previous discussion.)

* The "touchcancel" event is very narrowly defined here.  Should we 
leave implementers more discretion to cancel events for other reasons? 
(For example, if the browser window becomes hidden mid-touch, or if the 
hardware detects that the touch slides past the edge of the screen.)
