Generating random numbers from english text

Actually, if you've got an audio input on your computer, one way to generate 
"true" randomness for use in keys or whatever would be to turn on the microphone
and _speak_ about any topic for a few seconds, and take the MD-5 of the sound
file; the differences in voice, timing background noise, microphone quality, etc.,
ought to add a lot to the randomness.  (Or else, turn on the mike and type
N random characters and record them :-)
