Check ast-open[1] for the 3d command that implements the nDFS, or multiple dimension file system, allowing you to overlay directories. The 3d [2] utility allows you to run a command with all file system calls intercepted. Any writes will go into the top level directory, while reads pass though until a matching file is found. system calls are intercepted by an LD_PRELOAD library, so each process can have its own settings.
