I'd check out Revisor's source and see how they build CD images, build
something based on that. Also
https://hosted.fedoraproject.org/projects/pungi
This seems like it will almost certainly require a distribution that is
pulled in via a "cobbler import" so that all of the tree data is there.
It should also
look at the cobbler profile to determine what other repositories
("cobbler repo add") have been added to it, and also put a copy of
packages used in those
repositories on the CD.
You'd probably have to use something like pykickstart to parse the
package list out of the kickstart to keep the
CD images small -- or otherwise just require DVD usage. However
pykickstart won't run on the templates directly. Instead, look in
/var/lib/cobbler/kickstarts/$name and use the rendered template out of
there for parsing/inclusion.
I'd try this as a stand alone program using the cobbler API at first,
and if useful, it can be integrated into Cobbler later.
This is going to be more of an issue for me soon because I just got my
ks file as perfect as I can until some bugs are fixed on code outside
my control.
I was told to make the testing 'caveman simple' so 'plug in the cd'
seems simple.
Not as simple to implement, unfortunately :)

Not yet that I'm aware of. I still think this would be great and
you're welcome to start something. Possibly some way to integrate with
Revisor (though I'm not sure Revisor will be able to deal with
RHEL4/5)? See http://revisor.fedoraunity.org/
On a related subject -- I did know of one person looking at making a CD
that would allow syslinux type PXE behavior without the need for DHCP
blessed next-server, but that effort has apparently stalled. I still
think this would be great -- just build a CD image with a hard-coded
value for the location of the TFTP server ("cobbler build-netboot-cd"),
which would have the machine go out and PXE itself without the need for
PXE BIOS or a DHCP next-server entry. For instance, if your company
had a PXE server on your network you didn't like, usage of this CD would
allow you to install baremetal (using full PXE menus) from your own
internal cobbler server. If no one else picks this up, I'll take a
look at it somewhere down the pipe.
I see there are existing floppy disk images that do this with the DHCP
portion (for NICs that can't netboot), so all that seems required is
hacking the DHCP parts out and allowing a config file (or equivalent) to
specify the /tftpboot server -- so if you're sitting in your lab and
office, you can network install off of an arbitrary cobbler server from
bare metal without having to have the Cobbler server be blessed by
DHCP. This wouldn't even have to be something Cobbler specific but
would be insanely useful.
The non-network install CD/DVD thing is useful too.
