As someone else already mentioned on this list, fedora does not "require" that much RAM, but uses the RAM that is available to do the best out of it, eg. use it as a disk cache (which, btw, is a good thing to do when you use fedora from CD). Isn't it better to use all the available RAM to enhance your user experience instead of just letting it lying around unused? You can check yourself by using the 'free' command and checking the 'cached' column.
Comparing the system requirements of the Live (!) CDs with an installed version of Fedora 7 is like comparing apples with oranges. It is just the Live-CD "run from RAM" feature that comes with such enormous memory requirements.
