CGI.REMOTE_ADDR is the IP address
CGI.REMOTE_HOST is the host name if you have rDNS enabled on your Web server, or the
IP address if you don't.

Can't remember this one, or if it's even sent as a CGI var. Turn on debugging in CF
and see what's available. You should see all of the above vars come through as well.
If this IS sent as a CGI var, then check with different browsers-- IE might be the
only one that does this. Otherwise, screen size might be available in some newer
browsers via JavaScript.

Won't work. Client IPs are not unique. For example, all 15 milllion (or whatever)
AOL users go through proxy servers, so you actually see only a handful of IPs from all
of them (ok, a big handful, but you get the idea). Also, take any dial-in user--
someone from an ISP fills out your form, then someone else from the same ISP, who
happens to have been given the same IP as the first user when they dial in, tries to
fill it out and they will get denied, even though they're a new person. IMHO, cookies
are the only way to safely track users.
