request MAC recognition

[GoogleCodeExporter]

ability to recognise a network by the MAC address of an IP.

i.e.
I have a locked down network.  It has the same net/subnet as other networks i 
use.  The only 2 ways i can tell them apart are the MAC of the proxy server or 
if traffic moves with/without proxy settings.
