installing ports over a network?

[Don <djporter_(_at_)_socal_(_dot_)_rr_(_dot_)_com>]

I'm running OBSD 2.7 as my gateway/firewall, and it has a 2.7 ports
tree. Now I've added a networked laptop behind the firewall with no
cdrom and just a small HD. I want to install several ports to the laptop
but don't want to dedicate the space to a ports tree on the laptop.

Is there a way to install ports to the laptop over the network, kind of
like I do with a package? Possibly an NFS mount of a ports partition
from the firewall, or any other technique that might work? Thanks.
