This post is really just about an abstraction for storing objects and doesn't explain how you'd make data structures that distribute objects across nodes using remote pointers. Remote pointers end up being pretty nice for locality, since you can explicitly see what process a remote pointer is pointing to. None of the backends that my remote pointer implementations depend on really offer fault tolerance, though. So you're right: if you're in a situation where you have nodes entering or leaving your cluster before your program ends, this model needs extending before it works for you. That's true for MPI-style programs, generally, though.
