Hmm, I'm not sure I follow you.

When I say that hard links can't cross file system boundaries, I mean 
the linked files have to be on the same file system on the same partition 
on the same physical disk (lvm and RAID notwithstanding).  They can't 
just be mounted in the same directory tree.

Does that make sense?

So for the hard link method to work, /base needs to be a single file 
system.  You could check that in the 'mount' output, e.g.

I think hard links would actually work nicely in this situation.  I haven't 
tested it, but I think you would only need a single NFS export with the 
hard link solution, so the kids machine could mount the kidsmusic directory 
and nothing else.
