BUT why can't the person in question just rsync down the updates dir for the arch in question and make an iso out of it ... then mount that ISO themselves? Then CentOS doesn't have to try to spin, save, distribute, etc. all these ISOs. If I spin one extra CD (650MB) and distribute it to 200 mirrors (650MB x 200 = 130GB transferred) ... that ties up how much time and bandwidth for how many people and costs how many $. If 30% or more of our users were using it, it might be worth all that time and effort ... but it is also not hard to for any user to sync the right updates directory down (it already includes all the yum metatdata required) an burn it to ISO. I don't see ANY major distro out there that makes this available, because it is largely untenable to scale this to a million user scenario.
