It is not correct to call this my "suggestion." I was responding to a
previous post by Andrew Isaacson who said: "How useful would it be to use a
video stream as a source of random input to something like /dev/random?
I'm thinking along the lines of a Connectix QuickCam (sp?) or the cool
videocam that comes with the Indy...."

I was commenting on the sources of randomness, such as atmospheric RF
variations, antenna configuration, tuner sensitivity, amplifier noise,
etc., that would make prediction of snow bits very difficult.

As to suggesting setting the tuner to dead air, this was just one facet of
the discussion.

I have no brief with any of the proposed schemes: nearly any are better
than what we have now, if widely deployed and suitable used.
