Consider an end system which from outward appearance looks like a "router-on-a-stick" with a single physical interface, but inwardly is really a "host with embedded gateway function" per RFC1122. Now, consider that there may be an arbitrarily complex network of virtual hosts, routers and links within the physical host; perhaps using something like vmware or the Boeing CORE (http://cs.itd.nrl.navy.mil/work/core/index.php). Each of these virtual hosts can configure an EID address on an interface attached to a virtual link, and each virtual router can route between EID addresses and prefixes without ever pushing a single packet outside of the physical confines of the end system. That is what I mean by "node-local".
