This is a planned extension. The logic for optimizing message flow between multiple end-points on a wide-area network is similar to the logic for message-optimization on a cluster. This will allow submitting a query with a list of end-points. The query will then consider triples from each of the end points, as if the content of all the end points were in a single store.

End-point meta information, such as voiD descriptions of the graphs in the end-points, may be used to avoid sending queries to end points that are known not to have a certain type of data.
