Seems so. IIRC companies such as Panasas separate file names and other metadata from file storage. One way to get a single FS namespace that spans multiple disks or nodes for increasing data redundancy, file size beyond the largest disk size, throughput (and yes, complexity). Along these lines, a bit torrent swarm would make for an interesting experiment in distributed filestorage.....
