Exporting subdirectories yes - but exporting the same thing to differnet
machines ?
With regards to keeping things in subtrees the dentry stuff may make this
much easier dentries seem to make it realtively easy to ask
is_child_on(dentry,dentry)
with inodes you are sort of stuck which is why BSD and most other platforms
only allow export of filesystems not subtrees
