You could accomplish the same thing using static IP addresses and hosts
files. It would take less time to setup and there are less moving parts to
break. Just put every machine you own or that may connecto to your networin 
in the hosts file and copy it to all your machines.

If you often get visiting UNIX/Linux machines, you may need an internal
DNS. If the visiting machines are Windows, just enable WINS on a Samba
server and recent versions of Windows will use WINS to resolve DNS queries.

For small networks, DNS and DHCP are often more trouble than they're worth.
