There is a "mirror" method in apt since some time that is a bit of a
combined cdn/README.mirrors approach. Its not much used and probably
has some rough edges but should be a good starting point.
The idea is that you have a sources.list entry like:
deb mirrors://mirrors.debian.org/mirror sid main
and the server returns a list of "good" mirrors (based on something
like geoip) for your location as a simple text list. This is done on
apt-get update. After that it uses a selected miror of that list to do
the actual update and for getting the packages. The list is stored
locally in /var/lib/apt/mirrors so that a re-query is not needed for
each download request. It supports fallback to the next mirror if
there are problems and also reporting back issues (via a external
helper).
One missing feature is that it needs to send along info about the
release/arch its looking for or the returned list needs to be extended
to include this info. But otherwise it should be good and working.
