Some of the stuff he wants to do can be directly queried with Informant.
Also, Garth has been good at answering questions, way back when we
started to use it.

 Maybe looking at some of the Netflow products will give you what your
looking for to solve this problem.

Hello

You didn`t written system on which you want collect data.
On linux you probably can use iptables which provide counters about
packets/bytes matched by rule.
By ipac-ng software is possible to generate statistics per IP but I
don`t know if per port too.

btw. port 21 in FTP is used for control connection, data connections are
created on demand on dynamic ports. kernel module ip_conntrack_ftp could
help.
