Have you seen plasticFS
<http://plasticfs.sourceforge.net/plasticfs.html> by Peter Miller.  It
does shadow directories at user level on systems that support
LD_PRELOAD.  Actually, it currently works on GNU libc systems, but I
have heard of people working on getting it to work elsewhere.

It fails if there are statically linked executables being used.
