They are indeed just bigger ISOs. I've done NFS installs using a DVD ISO
so I'd expect a hard disk to work that way too.

I don't think it includes the metadata (the FC3 DVD didn't anyway).
However, that can be fixed fairly easily: if you've loopback-mounted the
DVD at (say) /srv/software/fc4/dvd then running "createrepo" in
the /srv/software/fc4 directory should create a suitable set of metadata
for using with yum.
