Some ideas were tossed around about recursive VFS modules at one stage. 
The way to do this is to have each module either perform the operation
itself, or call the next module to do it.  In practice you would simply
replace the current default ops structure with a paramater that
describes the next modules actions, allowing an infinite depth of staked
modules....
