5 percent of the mac addresses in a ADSL population used the same MAC 
address. Turned out to be some D-link device that didn't have unique 
address but they all had the same, and had a feature where you could 
"clone" the internal PC MAC address if you wanted to, otherwise it used 
some default address.

D-link support responded to customer inquiries with "yes, we know that 
they're not unique enough". Nuff said, avoid.
