Sounds like a good candidate for a CentOS Wiki page if someone can
document a clean way to do this.  The sipX kickstart may get you there
but is a bit confusing for this purpose.  [A related issue is creating a
DVD from CD images.  There's a blank page on the Wiki but no helpful

A work-around that might be a lot less work would be to just create a
CD/DVD (currently about 1.1 GB for i386) containing all the updates -
e.g. for the i386 updates, the top level of the DVD should have the
contents of the updates/i386 directory:  headers  repodata  RPMS

With k3b one can create this DVD quite easily by selecting "New Data DVD
Project", navigating to a previously-downloaded copy (or local mirror)
of the updates for the desired arch, dragging the 3 directories to the
DVD window, and selecting "Burn".

Can just install from the original DVD then reboot, mount the update DVD
and do 

# yum --disablerepo=\* --enablerepo=c4-media update

It would later be possible to mail your friend new DVDs when enough
updates, or important enough updates, come out to justify the postage.
