This is perhaps something we can trial. But it would make kernel.org 
quite unhappy. Also the other problem we have is that with over a 100 
machines in 80+ DC's around the world, just seeding the .centos.org 
network takes about 2 days. We did optimise some of the routes that we 
use and have been doing regular pipeline testing to see what are the 
best sort of rsync tree's we can setup, but 2 days is realistically the 
earliest we can open msync up to external mirrors.

Then there is the issue of non-public private mirrors rsyncing off msync 
and contesting with the public mirrors :/ Last time I checked ( and I 
accept this was a while back ) - we had about 3800 people pulling from 
msync, we dont have nearly as many public mirrors.

I know that Ralph is working on something of this nature, and there are 
atleast a couple more people helping and there have been some spike 
tests for various options. So its definitely in the pipeline, not sure 
if there is a delivery-date though.
