[Lilux-help] Dyndns protocol

Hello, I search for a solution to get the ip address of a friends dsl connection, but for a special reason I can/want not use classic dyndns.org What I need is more like a personal dyndns server. That means, instead of setting up his ddclient script to update members.dyndns.org, I want it to send updates to my ip and thus I need a service running on my box that deals with his updates. I found nothing on the internet that was dyndns2 compatible... does anybody know if something like this exists, or to I have to study the docs un how to create a dyndns client and write my own...?
