Unless I'm wrong, that script displays only that information for the viewer (so everyone will usually see something different), so unless the information is collected somewhere, there's not a whole lot it can do.

And I've seen forum software that collects IP addresses of posters, but it isn't much use for locating anything more specific than a city and identifying service providers, which is only really useful for blocking banned addresses.
