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 can't do this with a NetApp either; they max out at about 6TB now
(going up to around 12 or so soon). 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.
