The inbound packets can be source-spoofed, but full TCP links and return 
UDP will not reach the spoofer unless ARP poisoning or something similar 
enough is used. In cases of UDP being listened to without caring whether 
the reply gets to where it's supposed to go, spoofing will work. TCP? 
Not so much unless you can get into the network between the source and 
the destination and even then it's a pain. Home IP addresses changing is 
a challenge though.
