Does this have to be a single filesystem? If not, just provide a database front-end that maps some kind of resource identifier to the filesystem name. With that, you can span filers and/or filesystems. Seems like the only thing that would be reasonable.

You might want to talk to EMC and/or IBM, both of whom have *extremely* large filers. Your friend may also want to look at Traakan, who have a novel product in this space. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
