The attached snooping device doesn't need to talk, only listen. If it can be quiet, it need not reveal its MAC address, and hence not reveal its presence on the line. I have read that old style AUI cards have a separate "transmit" pair that can be clipped...I am sure that a suitable device could be constructed, including wireless LAN equipment with me on the receiving end a few buildings away.
http://www.shomiti.com and look for the Century taps. Puts a tap in a 10/100 UTP link and breaks out the full duplex pair (inverting tx to rx for one side) to two monitor ports while maintaining link. They are fairly expensive compared to a diode (although perhaps not by the time you get a diode in to a properly terminated Cat5 cable :-) if you value your time at all). The same can be done for fibre with an %80/%20 optical splitter from www.netoptics.com. Am a happy customer of both ...
