I think that shared libraries are NOT loaded entirely in memory.

As long as the daemons are doing mostly the same task, they should have
all of their required code loaded in memory.  I don't think it'll be a
problem.  But it would be worth testing it out.

If we move everything possible to media, how low do you think we can go?
I'd love to see the memory requirements drop to 32MB for a bare bones
firewall.

Around here a lot of places are dumping old Pentium 166 or 200 Mhz boxes
for as cheap as $5 US, and I know many people who are buying them to run
as Linux firewalls.  Some of these PC's don't come with a lot of memory.
Besides, a lot of the "competition" dedicated Linux firewalls, only
require 32MB or even 16MB.
