Yea, whatever API into the accelerometer is made should return some form
of condensed data but not necessarily be tied to the idea of gestures.
Different applications may want the data at the same time.
E.g. background car crash detector (that dials out and knows when it's
on the road) working concurrently with gestures for answering phone etc.
Maybe the sort of thing where an api would allow an app to register a
set of gesture, defined mathematically, and only one system process
polls for matching events. Doesn't sound like multiple processes
polling the data, or even processing the gestures, would work as nicely.

Letting the user add new gestures is a key feature IMHO. Also letting
them combine different gestures to new ones. We should make it easy
for people beaing creative with this. That's where innovation can

Also interesting. What I never understand completely is what kind of
cool stuff we can do with this. I mean detecting the ambient volume
level and adjust the ringing, etc is nice, but can we do more with it?
Fancy things like detect if we are in a car or plane and react
