I didn't think the Oceanstore paper was very interesting. Like you say, the naming scheme is like ours (and that is pretty much the obvious way of doing it). The interesting part is the paper they reference for their global routing system (which I first thought was just a hypercube mesh, but which is actually a lot more complicated):
