The difference being, when releases happen the public doesn't see what's
being released, where as the mirrors need to be able to see it. I.E.
rw------- <user> <group> centos/5.0
Would still be invisible during mirror propagation (rsync user is set as
a generic user without permission to access the folder) while the
mirrors connecting would be able to. That is the main difference,
otherwise 99% of the time the two would return the same data. Also
means that I can have two separate pools of connections say 10 - 20
slots for mirrors and say a hundred for normal downloading which gives a
mirror a MUCH better chance of getting into and downloading things vs.
the general public.

It would work for me, it might be useful to have those in a file that
also gets synced with centos (in the root directory) so that the other
mirrors can take advantage of the same thing?
Anyway - those are just my $0.02 anyway.
