...and here's a sample of the past 10 minutes or so of traffic. Each line is
one minute worth. ftp.cdrom.com pushed out 45GB yesterday (and that doesn't
include http and other traffic, just the total bytes of the files read).

This shows that the average is around 800K bytes/sec which considering the
relatively small size of the packets, is very close to ethernet saturation
(and ftp.cdrom.com isn't the only machine on this wire :-)).
