In the Fedora Core 6 install, it asked if you wanted to have access to the "extras". If you answered yes, it set enough networking to go out to extras to get the other packages. This means this capability is currently available in anaconda. With three separate DVD's for desktop, kde-desktop and server, why not use this functionality and and ask (say for the desktop ISO) do you want to include server features? and do you want to include KDE features? If the answer is yes, set up the link to the repos just like is done for extra's in FC6. This way you effectively have the full set of packages for all versions and if you choose wisely, the bulk of them will be on the DVD. Just my 2 cents. Bob
