Subject: Caching a sniffer

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.

   Simon
