This I think, highlights one of glusters few weaknesses - the 
inflexibility of brick layout. It would be really nice if you could just 
arbitrarily add bricks to distributed-replicate volumes and have files 
be evenly distributed among them as a whole. This would work 
particularly well with sharded volumes. Unfortunately I suspect this 
would need some sort of meta server.
