This too is a *fundamental* difference between QKD and classical

What does this "classical" word mean? Is it the Quantum way to say  
"real"? I know we're in violent agreement, but why are we letting  
them play language games?


IMO, QKD's ability to discover passive eavesdroppers is not even
interesting (except from an intellectual p.o.v.) given: its  
inability to
detect MITMs, its inability to operate end-to-end across across middle
boxes, while classical crypto provides protection against  
eavesdroppers
*and* MITMs both *and* supports end-to-end operation across middle
boxes.

Moreover, the quantum way of discovering passive eavesdroppers is  
really just a really delicious sugar coating on the classical term  
"denial of service." I'm not being DoSed, I'm detecting a passive  
eavesdropper!
