OK....

Sure, if you modify rc.firewall or use a different mechanism to
construct the rules.  The supplied rc.firewall is a shell script; see
".  file" in man sh for one way to read the contents of another file
into a shell script.

You could also generate the ipfw comamnds via some other (combination
of) (scripting) language(s), including Perl or m4 -- as long as
each such component you use is available at the time it is first
invoked (rather early in the boot process).

A lot is likely to depend on how dynamic the "grown list" is.

Peace,
david
