This has a problem if the EID is presumed to have continuity as the locator changes. I suspect that what you're really asking for is that if N systems are using the same IP layer address (improbable but not impossible), the router forward packets headed for it to each MAC Addresses. All except the first one would be forced to select locally-assigned MAC Address while in that subnet.
Not sure I want to go there, but the alternatives are: - ask the mobile system to change its EID in flight, contrary to ILNP assumptions, or - lose connectivity to N-1 of the N systems with the same address I suppose there is in fact one other possibility. The router could <violent handwaving> somehow come up with another subnet locator and put the new device into the new subnet. That would allow the systems to share a MAC address at the MAC layer and enable the end statins to differentiate between their datagrams.
