I don't know about an ILS that would do this, but there used to be an
open-source software package called The Distributed Library Project that was
geared toward this kind of sharing model.  Alas, I can't find any downloads
of the software online anymore, but I did find two instances of it running:

Also, someone has created a Wikipedia stub on Distributed Libraries that
mentions a site called Unlibrary that facilitates this kind of sharing.
