Does anyone else get really fed up with this analogy? Given that addresses aren't used contiguously its a really pointless thing to say; its more likely to engender thoughts of "why?" rather than "cool, must have". Better, I think, to say things like "IPv6 will enable people to easily create a home network environment with your computers, printers, personal communications devices, home theatre etc. [ie. auto-configuration], communicate and share with others using rich media [ie. no NAT] and make it more affordable to create rich content [ie. multicast, hopefully]... all without needing your ask your neighborhood geek."
