You mean 6lowpan type networks? I thought we had consensus to draw a circle
around them and
say, "put a device between that network and this."
I agree on 6LoWPAN: it has a clear gateway router, it's own routing
protocol, and should not be expected to provide an inter-Homenet link.
But you can still have various flavors of WiFi that could be acting as a
(marginal) inter-router link, in parallel with copper.
What about those? Are they also stub networks that only service end
nodes? How do you know? How do you avoid 2 routers forming an OSPF/RIPng
adjacency if it's a single SSID just within wireless range of each
other? That might be exactly what you want in some cases.

Streaming video != multicast. I don't think we've had any discussion of
multicast, except in
the context of mDNS. I don't need it in the home. Do you?
That was exactly my question. As a consumer I'd like video distributed
around my home available to mobile devices: I don't really care how it's
transported. The video may well arrive into the home via multicast over
cable via DOCSIS. The set top box is in the living room but my TV is in
the bedroom. Do we expect people to run the cable TV network to every
room to separate set top boxes with their own decryption cards and keep
this outside of Homenet? Do we expect AV manufacturers to always unicast
video within the Homenet? e.g. if I want my camera with my own copyright
content to play on a remote system? Or should we discuss whether the
choice of unicast routing protocol has a knock on effect to multicast
routing?
I'd like to keep things simple too, but I think it's an important
scoping question to get clear consensus on.
