I don't have a problem with it being taken out, as long as something better
replaces it.  Just removing it would bother me.

How about we first ask the user upon install if they want to be able to accept
outside connections at all.

I think this thread could be solved by designing a few types of installs and 
giving defaults for host.deny and host.allow and other security points for each
install scenario.

	Basic Install - Workstation (no access) 	
		host.deny: ALL: ALL
	Basic Install - Workstation (some access)	
		host.deny: ALL: PARANOID (or IPs)
	Basic Install - Server (some access)
		host.allow: ALL: ip list for accessible points
		host.deny: ALL: PARANOID (prompt user for preference)

	Expert Install - Asks user what they want, IP based or paranoid or none.

We *need* a "secure by default" install option for people that may want to use

What does everyone think of a /etc/security.policy file with a few security 
flags set upon install that packages can read during later installs or 
upgrades to see if they should be open or closed by default?
