Vaguely related, if anyone is interested in tracking their own typing (and individual key counts) check out http://whatpulse.org it's pretty great :-) (my profile, http://whatpulse.org/stats/users/210575/)

...so this captures every key and mouse movement on your computer, then sends it to a 3rd party server for 'analysis'.

Seems legit.

I realize you're probably joking :) but the software just "pulses" the number of keystrokes and clicks to the server whenever you tell it to.

It can generate keystroke data like this, but the data is stored locally.

Almost any software you install could potentially be doing that.
