I wouldn't want to redirect every hit, or even count everything through iptables,
the overhead seems to high to me. Instead we track bandwidth only when it
actually matters, and we do it using a custom Apache module. This is something
we worked on for a few years, so you may find that it makes much more
sense to take advantage of all of the time that we spent on this, all of the
research, the discussions we had with university professors about declining
averages, etc. rather than either doing all of that work over again yourself
or skipping the hard part and building something that doesn't work so well.
