The situation we have here is multiple 6-9TB raid5 arrays on two different 
machines.  These are available on our network as /data/cora#.  I also make 
available a merged tree using symbolic links to the highest unique file or 
directory as /data/cora that I create using the attached script, as follows:

/usr/local/bin/mktree /export/cora /data/cora{1,2,3,5,6}

(I don't currently have a cora4)

You could probably do something similar.  The /export/cora directory is only 
writable by root.  One issue with this system is that if a user is creating a 
new "top level" file or directory they still need to do it directly in one of 
the constituent directories.
