It works sufficiently so far.  I'm curious about your mention of NIC's and 
IP addresses.  In my situation I connect to a cable modem.  However, that 
connection is wireless/wi-fi (802.11b router, 802.11g adapter).  The 
adapter is an Asus WL-330g which connects into the RJ-45 type ethernet 
adapter.  As far as linux is concerned, the connection looks like a wired 
connection.  Of course, the router uses DHCP.  So, the IP address for the 
NIC will move, being dynamic.  The eth0 NIC has dhcp enabled.

here's what I have:

[thufir at arrakis ~]$
[thufir at arrakis ~]$ hostname
arrakis.homelinux.org
[thufir at arrakis ~]$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=arrakis.homelinux.org

[thufir at arrakis ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

127.0.0.1               arrakis.homelinux.org localhost
