the interfaces is a slowly moving target. i'd avoid this unless you were
constantly tracking ipfw changes (i.e. you were writing something that
heavily interacts with ipfw and not just trying to add a firewall rule
as part of a much larger projects).

'libipfw' is something that should be written at some point, but until
we have multiple consumers of the 'api' it isn't really a priority.
