I agree with Christian. I am unsure why your metagrid would do any
partitioning - isn't that the
job of the underlying host grid? Changing the geometry does not change
anything in the load balancing and
seems no reason why a GeometryGrid type omplementation need to implement
anything in a grid
distribution....
