	    <address>Serving Machines IP</address>
	    <localaddress>127.0.0.1</localaddress>

I'd say better use the server machines ip address on both (instead of the 127.0.0.1 loop) If he has a DNS, he can put in the first , if not , just repeat them. For Public login, he probably can just quote them out;

	   <!-- <address>Serving Machines IP</address> -->
	    <!--<localaddress>127.0.0.1</localaddress> -->

This works best for Local and Lan Play. If you use the 127.0.0.1 loop, then you would only be able to play a client from the server machine. But the regular Lan IPs will enable play from anywhere;

	    <address>my.dynip.com</address>
	    <localaddress>192.168.0.100</localaddress>

if just local Lan play;

	    <address>192.168.0.100</address>
	    <localaddress>192.168.0.100</localaddress>

That's if your server machines ip is '192.168.0.100'

The only good reason for using the localhost ip (127.0.0.1) would be for the database, as it would help protect it somewhat if you only gave 127.0.0.1 access permission.

        <database>
                <host>localhost</host>
