This is a continuation of DM-779, continue research related to data distribution and replication. There are still many option questions: should it be centralized or peer-to-peer? Is bittorent useful? How much should be home grown vs off-the-shelf (and which off-the-shelf). There are no direct deliverables in FY2015, but it is a complex topic, so we should not wait until the last minute. This epic covers the R&D / design.
