Personally, I think an export option would give the most flexibility.

That would allow the sysadmin to, for instance, put a set of libraries
+ executables that are shared by all clients on one volume which is
exported in the normal fashion. Then putting files that are typically
just accessed by a single client, or that are too huge to fit in cache
memory on a separate volume that could be exported with the new option
set.
