    Technical Paper (Not by any stretch of the imagination difficult or indeed technical)
    University Article
    Slashdot Article

    This was on Slashdot a few days ago, and the usual elitest sector shot it down, in many cases without - I believe - an thorough understanding of its principles. Some of the "obvious" methods of breaking the system displayed a poor knowledge of electrical principles and/or stochastic noise theory.

    The best comments referred to inherent *difficulties* in implementation, rather than absolute problems in the scheme. For instance, although in practice it might be possible to monitor the transport medium at two points - as suggested by several people - it is theoretically impossible to do so without altering the system, however slightly. (Passive coils for example). There was an insightful comment on using natural gaps in detectability involving nyquist rates - again an implementation issue. The smug select postulated vaguely that theoretical absolute security just doesn't exist and that this is just another false dawn.

    What do the educated/unwashed masses of the engineering board think?
