All of the ones within reach of me -- www.ics.uci.edu, www.w3.org,
and a few other less public ones. Hits received on the server are
important for load reasons (which is why I wrote wwwstat). Hits
received on the proxy are amusing, but not necessary for anyone
operating a non-marketing-oriented service.
I'm not sure if that qualifies under "most" anymore, but it did
the last time I checked.

If you are already doing one batch report, why not do all the reports
that way? The larger the report, the better encryption you get.

Horizontal Tab (I was speaking BNF-ish), and on a per-hit basis.
