Hi,
We are not preventing anybody from doing anything, as long as they do 
not hit our servers to hard.  You can use mrepo, cobbler, yam, sweat 
potatoes, and anything else you want.  (Sorry, sweat potatoes is not 
really a program, it's just that everything else diverged into food, and 
then I got hungry.)


mrepo and cobbler are not true mirrors.

Yam & Mrepo - "mrepo builds a local APT/Yum RPM repository from local 
ISO files, downloaded updates, and extra packages from 3rd party 
repositories."

Cobbler - "Cobbler is an install server." & "Cobbler can also optionally 
help with managing DHCP, DNS, and yum package mirroring infrastructure"

They download packages and then create their own repositories.  They 
might even pull in different packages from different places and merge 
them into your repository.
A mirror looks just like what it looks like on the server you downloaded 
it from.

So, in summary.  You can use whatever program you want to pull packages 
down.  Both mrepo and cobbler can use rsync, so I would suggest that. 
But I'm not going to document how to use either mrepo or cobbler.  For 
that you will need to look at those programs documentation.
