It would probably be better to build it at the switch level.  I would think
there would be a change in resistance when there is ANYTHING added/removed
from the cabling that could be measured by the switch.  You could then have
it disable that segment upon such detection if you'd like.

Hi,

I wonder whether it would be feasible to build network cards that could
report the signal reflection characteristics of the link to make it
possible to detect sniffing equipment cut into a network cable (should
catch magnetic coupling as well).

I bet some security conscious folks will pay lots of $$$ for that.
