Hrrmpf ... whenever you think it can't get worse, somebody comes along
and proves that you're wrong ... :(

Using the IP to "identify" a user is even more unreliable than anything
else (even session counting would get you closer to the reality). There
could be a hundred visitors on your site using the same IP (proxies) or
a single visitor using multiple different IPs (dialup, load balancers).
Back to rand() again.

OK, next try. Who wants? SCNR

Correct. And in practice it simply can't work.
