The iso image which is available for DL is old and not easy to configure. It is not for the average user. I am currently in the process of reworking the entire tree (you can browse it in CVS, the module is Prometheus)
If you do DL the current iso image, please note that I cannot help you with installing it. I am currently too busy trying to get the newest version up and running.
Please be patient.
Help with development is always appreciated though!
