Urchin can do this a much better job if you ask it to, take a look at http://www.google.com/support/urchin...y?answer=28710

In order to get the advanced tracking you need to add a
script to each page, which sets and reads cookies. Even Omniture requires that.

If you don't want to bother with that Urchin can give good statitistics
but of course it can be fooled, as you point out.
