Here's some feedback : tapping the spacebar with the phone? That's dumb. Why? I have to hit hard for the "bump" to happen. But that's not really a problem since hitting a keyboard with a cellphone makes no sense. Consider another scenario :

a) The user clicks somewhere (or vocal command?) to enter a listening state.

b) Then he shakes his phone.

But then you lose the thing that "magically" links the phone to the computer, i.e the simultaneous record of the event occurence.
