How is this different from things like the Sistina / Red Hat GFS?

GFS runs *atop* some distributed block device implementation (once iSCSI only, but now NBD+dm as well), and provides shared locking and so on so that lots of systems can access one filesystem at once. It could just as well run atop this (well, patches would probably be required since currently clustered LVM is utterly dependent upon dm, but I don't see why you couldn't run dm atop this as well.)
