I have a related question: if your network card is in promisc mode and 
assuming you can see the packets at all (because you're on a hub or 
something), and someone sends a packet with a MAC address that isn't yours, 
but that is addressed to your IP, what is the typical response of the network 
stack? Ignore it because the MAC is wrong, or accept it because the IP 
address is correct? Does this behaviour vary based on configuration or OS?
