A few things: keystrokes is only part of the data collection. I wouldn't be surprised if they're also looking at mouse movement, or the actual keystroke pattern (backspaces and such). But it does raise an interesting idea: build a fuzzer that you can use to change "profiles". Rather than making yourself mechanical, put on a different face. Also, I'd like to see a concept website that used keystroke data to authenticate a user instead of a password. Basically, give them a "passphrase" or somesuch that is presented in cleartext with the instructions: "type this phrase".
