Now that April 1 is far behind, I'll mention that I've been looking
at ways to amalgamate the mechanisms used by ipfw/ipfilter to address
this problem.  Without being insulting, my 5 second grab on this is
that ipfw has grown like a tumour inside the ip stack with bits and
pieces hooked in here and there and everywhere (exageration.)  That
is to say I think should be and can be better than they are.
