- I don't believe it's possible in general. Certainly no software ( since
- the hardware port has to be sufficiently robust to handle an arbitrary
- number of legit "taps" already) and even with hardware, I ccan always
- make the impedence of the tap sufficiently high so as to be invisible
- in the normal variations of the ethernet. Unless of course you use
- quantum ethernet ( Pat. Pend. -)
