dynamo holds a pointer to an object in s3 which records an ordered list of bundles. compare-and-swap ensures that if two simultaneous pushes happen, only one will succeed. the other will have to pull first before retrying push. there are actually a lot of providers with s3 and dynamo compatible apis. otherwise, fork and implement new provider! git-remote-CLOUD.
