he could take this even further. by changing his mac to one already on the local network, he has the beginning of an ARP spoofing attack. essentially it modifies the ARP table on both the target computer (the one u want to hack) and the local router, so all traffic between the two is passed through his machine. once this is setup, passwords and other goodies can be intercepted, and stored for later cracking.
btw, once he's modified his mac to one already on the network, they other person is going to have a denial-of-service. they will not be able to send or receive anything, unless he is successfully routing traffic by the above mentioned ARP cache poisoning. he would actually be better off sniffing the credentials people log in with to access the network, that would be the least intrusive.

very nice. i thought MAC addresses were burned into the ROM or something and couldn't be changed though.
there are a lot of programs out there that can broadcast whatever you want across a network
