Hi there.  I've had such a system operating on my web-sites
for a year or two now.  My system both collects the Referer:
fields and confirms all the links, actually downloading each
page to see if it really contains the link.  (Many browsers
seem to emit spurious Referer: fields -- for example, to the
last document shown even when the user is typing in a new URL
entirely.)  It checks for mirrored pages and maintains a notion
of the reliability level of each backlink.

The results are always interesting.  You can try visiting my
pages at http://www.lfw.org/.  The word "backlinks" at the
bottom of each page is linked to the list of backlinks.  (I
grew tired of dealing with two auxiliary files, so now it's 
just a single file containing both the access stats and the
backlinks.)
