As a possible consideration: as far as I can tell, multitouch devices come
in two forms; those with explicit coordinate spaces that match the screen
(touch screen overlays, e.g.) and those that are just track pads that
don't have any explicit relationship to the screen (e.g. Powerbook track
pads).
I agree it would be cool for DOM applications to have access to this data.
What we need is a concrete proposal. I imagine this would originally be
its own specification, since I presume we don't want to add this to DOM3
Events (thus avoiding feature creep).
