I do think more will be achieved by making network installations
convenient than putting a hard limit on the disk number. After all even
if a floppy FC was possible today no one would go through the hassle of
feeding hundreds of disks in the reader to make use of it.
Just have the network install kick ass (a one-stage install from the
first CD not like I heard minimal install then boot then yum then
whatever) and no one will care the about number of isos anymore (because
mags will only ship the first CD and people with no network connectivity
will the the last to complain FC isos are numerous enough they won't
miss anything once they burnt them).
Network install is fine for those that have big network pipes. Some of
us live at the end of a crappy 28K dialup because we have 25Kms of
copper from the exchange and the encumbant Aussie telco won't do
anything about it :-)
