It is a matter of taste.

I don't like the idea, because I think it is faster and easier to
answer just by pushing a button (or button sequence, if you like).
And the "typical movement" will be hard to detect under "moving
situations" (bus, subway, walk, run, in a car).

Great ideas!, I just saw them.  The smoke sensor can be made,
freescale sell some really small of these.  And a "mesh" of these
devices, or a "radio beacon" could be useful to locate people when
they are out of the coverage area.

The more complicated it is, the harder to make it work under "moving"
situations: say, when you are in the bus.  See, How can I make the
phone to be "steady" for 3 seconds if I'm in the bus?, I just can't.
Even as a game controller, it would be a problem, but it would me more

Anyway, I don't like the idea, but other people may like it, and if
you have the SDK, and API access to the accelerometer outputs, then
you can implement it and use it!.

It can be done, you just need to filter-out the disturbances.
