I used to nfs mount /usr/ports and run a cron job on the local machine. I made
a file on the local machine:
echo 'This is a mountpoint' > /usr/ports/KEEP_ME_EMPTY
The script would:
if [ -e /usr/ports/KEEP_ME_EMPTY ]; then
do_nfs_mount();
if [ -e /usr/ports/KEEP_ME_EMPTY ]; then
give_up_or_wait();
fi
fi
Of course it's fragile, but it works for not so critical issues.

Problem with today's modular software: they start with the modules
and never get to the software part.
