Same here, hence the suggestion of using P2P software (BitTorrent) for letting clients fetching the data from each other (together with initial entrypoint for the deployment, obviously), and you'll avoid the congestion issue as clients will fetch the data from whatever node is nearest, and configured properly will only fetch data outside the internal network once, after that it's all local data transfer (within the same data center).
