Share a file to another user on Linux

I have (unmodifiable) server processes running on different tcp ports as different users. Scripts running as nonprivileged users need to pass filepaths (readable to them) to the server processes. The filepaths are likely to be unaccessible by the server processes. The scripts could copy each filepath to a shared location (/tmp/something/) and pass the shared filepath instead. Can I achieve the same effect without copying files? Hardlinking may not be feasible as filepaths will likely be on a different filesystem than the one /tmp/something/ is on.
