What sort of network are you talking about? I know my wireless router 
has the ability to block off computers based on their mac address, and 
the wireless router admin page also gives me the ability to find out a 
mac address using a particular ip. If you are running your own dhcp 
server, the leases file will give the mac address of the computer using 
the ip address, and then you can deny service to that mac address. Are 
you using a dhcp server, or how are the users getting their ips?

Hope this helps,
