You can overlay your naming FS on top of an existing disk based FS. In effect each named file in this naming FS maps to a canonical name of a disk based file. You can implement linking via a ctl file or something. Is lnfs(4) a relevant example?

that certainly does seem like the hard way to do things. why should the structure of the data depend on where it's located?  certainly ken's fs doesn't change the format of the worm if you concatinate several devices for the worm or use just one. This would be a long discussion :-)
