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.....
