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?

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!
