make it a port / package first.....
then it can be tested more..

it just comes up for me...
man 4 divert
DIVERT(4) FreeBSD Programmer's Manual
DIVERT(4)
NAME
divert - kernel packet diversion mechanism
SYNOPSIS
#include <sys/socket.h>
#include <netinet/in.h>
int
socket(PF_INET, SOCK_RAW, IPPROTO_DIVERT)
DESCRIPTION
Divert sockets are similar to raw IP sockets, except that they can
be
bound to a specific divert port via the bind(2) system call. The IP
ad-
dress in the bind is ignored; only the port number is significant.
A di-
vert socket bound to a divert port will receive all packets
diverted to
that port by some (here unspecified) kernel mechanism(s). Packets
may
also be written to a divert port, in which case they re-enter
kernel IP
packet processing.
Divert sockets are normally used in conjunction with FreeBSD's
packet
filtering implementation and the ipfw(8) program. By reading from
and
writing to a divert socket, matching packets can be passed through
an ar-
bitrary ``filter'' as they travel through the host machine, special
rout-
ing tricks can be done, etc.
etc.
it's in the tree....
