What about traffic that doesn't go through squid?

netfilter byte counts are good enough for our billing purposes.  I don't
believe them to not properly record packet length.

I think ULOG and mysql is going to place unnecessary overhead on the machine
doing the counting though, but I am not familiar with its use.  I use
ipac-ng to periodically take the byte counts from netfilter and put them
into a database; ULOG sounds to me like it'll try and log the size of every
packet that comes through the machine at the time it comes through, which is
a lot of transactions per second.
