There are platform independant tools that could be used to make the
fw-builder so that even Mr Macuser could run it. I've written python apps
that run unchanged on all platforms both with and without GUI's. However,
I'm not sure unskilled people would want to low-level configure and
tweak their firewall anyway.

And if you don't have gcc, you can't compile a leaf kernel. That doesn't
mean you can't download a pre-compiled one.
Perhaps firewalls have reached the point where they have become so complex
it's up to the experts to design and tweak them, so that the majority can
pick the one that best meets their needs. I dunno...
I just suggested this because it seemed a logical (but perhaps compromised)
solution to the tool complexity vs tool size dilema. In any case, I think
it's a good idea to seperate the fw construction/configuration tool from the
fw model/implementation, even if they do both end up on the leaf machine.
But the first thing to do (as others have pointed out), is define the model
before getting tangled up in implementation details.
