Something even less implemented was talk of interfacing to some replica management system which would be aware that the same data could exist in multiple places and do useful things based on that. Useful things might be only running on sites that already had the data, and staging from that site's store (which integrates replica location into the pick site / stage data / run job process at at least two places)
