I'm not interested in precise utilization which is why I tally both
directions under the same counter - I'm only interested in approximate
utilization.

Has anybody written up a nice accounting package?  I've got a quick'n'dirty
hack that consists of

#! /bin/sh -

PATH=/bin:/sbin:/usr/bin:/usr/local/bin; export PATH

cd /var/netaccount

(
ipfw -s -a -n l > `date +%H`
ipfw z
) 2>&1 > /dev/null

exit 0

run once an hour out of cron...  it allows me to look back on the last 24
hours on a per-hour basis.  I have a cheapie set of grep/awk/etc scripts
that go through and generate GNUplot data (whooopie!).  I monitor traffic to
about 10 different major subnets here.

I'd really like to keep much more detailed statistics with a much finer
resolution (5 min?)...  but the tools to do this in a practical way
don't exist.  I'd like, for example, to be able to pull up a graphic showing
off-site NNTP traffic for the last 30 days, just by clicking a few buttons.
