If you copy the installed applications, you don't have to copy /usr/ports.

Ports and packages install in /usr/local by default. So after you have
built/installed all ports on the first machine, use tar(1) and nc(1) to copy
the whole /usr/local tree over. Subsequently, after you have updated the ports
on the first machine, use rsync(1) to keep both copies syncronized; that is
much faster than copying. (In this scenario the second machine doesn't need
/usr/ports or /var/db/ports and /var/db/pkg at all!) Remember to enable any
daemons in /etc/rc.conf as necessary.

Alternatively, you could use nfs to export /usr/local from the first to the
second machine. But this will probably be significantly slower in day-to-day
usage. And if the first machine is down, the second one looses its ports. :-(
