    However, those aren't the main failure modes you need to be concerned
    with. Antenna effects may actually be your biggest problem -- picking
    up deterministic signals from other parts of the system.

    However, I believe this is a solved problem. It would definitely be
    interesting taking rngd and figuring out a way to drive it from /dev/dsp
    -- probably not too difficult a modification.
