Let me rephrase.  Only one machine on the network having a modem.  If you
only want to use the Internet on one machine you probably don't have a
router, but might have other machines, printers, etc. that need zeroconf.

I just saw a post in HP's forums asking what Jet Direct devices are
compatible.  I think you will find a lot of small Apple networks relying
on it.

The goal of zeroconf is to have... well zero configuration.  Having it
enabled by default means it is available by default without any
configuration.

I think if your firewall is allowing connections you don't want you have
bigger problems.

Nothing about zeroconf changes the basic TCP/IP.  Again, to paraphrase
http://www.zeroconf.org/, it just:

a) finds an unused address
b) allows you to do name resolution without a specific DNS server
c) find out what other services are available.

It's basically a better engineered version of Netbios over TCP/IP.
