If you are supporting multiple users and, especially from a, presumably 
poorly connected location, you should be running an external caching proxy
and firewalling the site to prevent that proxy being bypassed (you will
only get the full benefits from an external proxy in this case (unless static 
pages are only ever accessed in one session across the whole site), so the
arguments about whether caching support should be bundled don't, I believe,
apply).

All the proxy servers that I am aware of maintain extensive logging of
URLs and bytes transferred (although they may not always provide byte
counts for aborted transfers - and the W3C one, at least, doesn't log
the If-Modified-Since request if it revalidates a page, and gets 304
unchanged response - it does log the transfer of the cached copy to the
browser).  Firewall software may well also give you
overall byte counts which you could use to calibrate the proxy logs.

The most common free (Unix) proxy these days is probably squid, although
I've been using the W3C one in the office.

The analysis software that exists for analysing incoming hits on a web site
can also be used for analysing proxied accesses.
