I *think* autofs5 allows for $UID/$GID in mount maps to provide different mountpoints - but that only gives you a whole unique tree not individual files. Depending on the number of files you wish to be unique for each user you could perhaps use a symlink for the file which then points to an autofs5 map with a $UID in it. You may need to use --bind mounts if it points to a LustreFS.
