But the daemon has the index, which is indexed by a sort key. If sorting
is done by the application, it cannot utilize the index. If sorting is 
done by the daemon, it can at least use the index itself to retrieve 
the sorted data. It should also be possible to return the reverse order
of the index quite efficiently inside the daemon.
Or is this already the case?
