Ok, attacks are limited to people that you share a router leg with. On
a broadband ISP that could be several subnets that appear to be on
separate lines but are not.
The most likely exploit would be the WIN-POPUP spam. But who knows what
other holes that a virus might be able to exploit.
Since the subnets rarely connect to each other, the symptom of duplicate
traffic from the "router on a stick" configuration usually does not
apply. ISPs do this, but a campus LAN would not.
