...except that even if you are not transmitting, you are still
establishing carrier. In a *really strongly controlled* environment, a
switch port that was live but was supposed to have no hosts attached
would be a give-away. In a *paranoid* environment, the loss of carrier
(while you attached a hub to the live port) without explanation would be
a give-away.

So what you would have to do is find a live cable, and do something like
use inductance to reproduce the electrical signal in the cable, and then
could monitor the connection at will.

In a *dead paranoid, tempest filled environment* its all fiber, of
course...
