i like this idea.  here's my improvement: pair the normal 
password/passphrase with voice data.  just like in my current phone's 
address box I can add voice to an entry, a moko user could add "voice" 
to their login credentials. on those days when you have a sore throat or 
you're in a noisy place, the text password could be tapped in.  but 
normally you would press a button, "speak the password, and enter"--LOTR

even more elegant: if the voice credentialing subsystem used PAM (a must 
in my book) then the voice_auth PAM module would be a simple config in 
pam.d, added as "sufficient" for auth.

thoughts?
