You make it sound like a hard thing to do.  It is a couple of commands and 
putting the directory to share in a file.  Something you could easily do on a 
laptop if nothing already exists, but in most places it is extremely convenient 
to have one or more directories that are shared by both samba and nfs so you can 
download or copy files from any OS and access them from another without having 
to set up something special each time.

Maybe, if you have extremely fast and reliable internet service. I don't think 
you can pick up where you stopped after an error.  Everyone's situation is 
different, but disk space is usually cheaper than internet capacity and you can 
use bittorrent to let the CD isos dribble in over about any kind of connection - 
and once you have them, you can carry them with you on a laptop drive (or a 
phone's micro-sd these days...).  Anyway, my impression is that for installing 
your 2nd through some moderately large number of machines that don't have DVD 
drives, an nfs install is as easy as it gets.  For very large numbers where you 
don't clone disk images you would probably set up local repositories and 
something like cobbler to control pxe booting to a kickstart file.  (You can use 
kickstart anyway, but without the pxe boot you have to type in the url to the 
file that you've dropped under a web server).
