To boot the install from the network, you'll need some hardware that supports network booting, tftp (a very simple ftp), and dhcp. This howto
has got the details but no explaination. Follow it but substitute the vmlinux and initrd.img files from the images/pxeboot directory of your Fedora CD. You will need to put your install images somewhere. I think you can put the ISOs on a ftp, http, or nfs server and specify network install when the installer starts.
I haven't done this, but it looks interesting.
