to your last question, i do think that residential users will have

city-wide L2, simply because the broadcast domain for things like
Bonjour

"routers"
as their preferred security perimeter (vs hosts, bridges, or
repeaters.)
I'd like to note for the record that Bonjour is more than just DNS-SD
over multicast. It works quite well over unicast with infrastructure
content servers by using a few simple extensions to the core
protocols, e.g. for handling long-lived queries, etc.
In the unlikely event that metro-L2 came to be feasible for other
reasons, there wouldn't be that much of a problem fitting Bonjour
into that environment. While Bonjour was developed for zero-
configuration networking, it's still perfectly reasonable to use it
where in managed networks.
(these are the wages of our sins from not separating routing from
identity,
and from assuming that the economic principles underlaying IPv4
routing
would still apply in an IPv6 world.)
Here here. This argument seems awfully compelling to me. Given the
near ubiquity of IEEE 802.1 for local-area networking in residential
and small office environments, it's really hard for me to see how
there is a need for residential users to have routed networks when /
64 prefixes are almost too cheap to meter (and will continue to be
until kakistocracy emerges as the dominant form of Internet governance).
I don't see why residential users should even need ULA, much
centrally assigned ULA. Is there a thread on one of those ops list
someone could refer me to read from the archives so I can come up to
speed on the reasons the operations community thinks otherwise?
