I'm not sure if this answers what you want or not, but I just use rsync
and point it to a lower level mirror as per the CentOS folks wishes.
Put it in a bash script, enter it into cron, and then it syncs every
night with a mirror of choice. There's nothing to worry about
configuring, except an exclude file.
For example:
/usr/bin/rsync -v -r -t -p --delete -l \
- --exclude-from=/usr/local/etc/centos.exclude \
rsync://one.of.the.mirrors/centos \
/srv/centos/updates 2>&1 >> /srv/centos/logs/rsync.log
My exclude file then skips all x86_64, SRPMS, ia64, isos, ppc, dvds,
etc. and just pulls the rpms and whatever else I only need. Whatever you
want to skip you can just put in here. Of course, this gets just the
base CentOS stuff. You can even skip by release if you wanted to only
get 4.4 stuff.
Then, I have a similar rsync going then to pull things from rpmforge
that I want, because I don't pull the entire repo. I only pull, again,
what I need to save some bandwidth.

I don't know exactly what you mean here, but the initial rsync will be
large and consume a lot of time, but then after that rsync only grabs
the files that have changed. So only the rpms that are new and changed
will be downloaded in subsequent syncs.
I hope this helps you a little. This is how I create a local yum mirror
without the hassle of configuring a lot of things. If I recall, the
CentOS folks just don't want you pulling from say their main mirror,
mirror.centos.org, but instead pick a public mirror.
Hope this helps you. Let me know if you want to see the exclude file.
Regards,
Max
