The easiest solution would be a to nfs mount the directory from a server

I this is not possible you may want to intercept file requests to the directory
and map the requests to a multi-level directory structure.
(Example:  directory/filename =>  directory/hash(filename)/filename )

File requests can be intercepted on multiple layers - from inserting dynamic
libraries to layered file systems. (with lots of possibilities between the 
layers)
