But creating a solution where you can talk to anyone else on the Internet 
but not the ones in your own neighborhood is broken, so it needs to be 
fixed. In IPv4 I've seen this solved with local-proxy-arp within the 
subnet, and for IPv6 it's easily solvable by not announcing an on-link 
network so they won't even try to communicate directly with each other but 
instead everything is routed via the ISP upstream router and then down 
again to the other customer CPE/computer.
