One way to differentiate between machines behind a NAT would be to use a non-unique identifier to separate machines -- e.g. using the last 1, 2 or 3 bytes of the first Ethernet card.
That way you could tell if there are 7 different machines behind a NAT, but you wouldn't be able to use the number to uniquely identify a user. -- and if you have a dynamic IP, the next time your ISP gives you a new IP address, you disappear into the morass.
