My experience has shown that most ISPs don't really care whether or not you actually have more than one computer, as long as you don't have more than one machine trying to get addresses from the ISP's DHCP server. If the AUP/TOS specifically says you're not allowed to NAT, then ideally you should find a new ISP if that's an option. If the AUP/TOS does not say so, then the number of computers you have running is really none of their damn business. -- Shawn K. Quinn
