i would hate for people to think that a middle box is
required, when the best place to provide security is in
the host.  Other layers are needed as required, but it
is sad that we don't look to the host it self as a first
step.

I would support adding security at the host-level, 
especially because with a centralized firewall, internal 
infrastructure is usually left wide open to internal staff, 
with trust being the rope we all hang on to to keep things 
running.

However, if pratical running of the Internet has taught us 
anything, host-based firewalling (especially in purpose-
specific devices like printers, Tv sets, IP phones, IP 
cameras, e.t.c.) is a long way away from what you can get 
with a centralized firewall appliance. 

Do I like it? No. I run a simple packet filter (IPfw) on my 
MacBook - it does what I need. But we know Joe and Jane 
won't want things they can't click; and even though they had 
things they could click, they don't want to have to 
understand all these geeky things about their computers.
