I think it's a great idea and would go a long way towards making things
more usable.  One of the questions is do you do the firewall change on
service start/stop or at chkconfig time.  And I'm a little bit torn on
that one.  chkconfig time makes it "simpler" as far as not requiring
initscript changes.  start/stop seems like it's probably more "correct",
but would then require initscripts to call a new function on start/stop
