Use case: bandwidth efficiency

This is a use case I havent seen raised - I hope its not too late.

In CS AKTive Space (http://cs.aktivespace.org/) we do a number of queries
along the lines of: (in RDQL syntax)

SELECT ?uri, ?name, ?worksfor
WHERE (?uri, <rdfs:label> ?name),
      (?uri, <x:worksFor>, ?worksfor),
      (?uri, <x:worksInArea>, <http://exmaple.com/research-areas#CS>)
...

Returning several hundred rows. Currently the limiting factor for
performance is generally bandwidth, as the client has to receive a
packaged up representation of the results. 3store uses a not especially
efficent XML encoding for result tables.
