Replying, changing the very misleading subject. Thanks for the comments, please see inline.

While we should aim to create technology that is generally useful outside the home, the defined scope is the home. Among other things, this should help underscore the auto-configuration requirement as the further you dip into SOHO territory, the more likelihood that there is an administrator of some sort (whether it be a remote worker's IT department or otherwise) becomes more and more prevalent. While the "SO" absolutely must be able to work with our "HO" (what looks to us like a special type of additional ISP, if you will), we stop short of, say, trying to define the VPN router's security policy or whether it should use IPsec Tunnel mode or GRE with Transport Mode or SSL or... (Personally, I would like to see homenet's technology have impact outside the home - we're tackling some important problems IPv6 has had for a while.) > * Note - some devices today can only utilize a /64 and nothing more these > would not break. Good point, and this brings up a general issue of working with existing non-homenet routers that support IPv6. The document should probably highlight this. > * No NPTv6 please Section 2.4 "As such, neither IPv6 NAT or NPTv6 is recommended for use in the homenet architecture." > * ULAs support could be introduced at a later date Why wait? > * Agreed regarding bridging avoidance > * How is "relatively stable prefix" defined? Relative to changing the prefix whenever the CER is reset: "Some ISPs may offer relatively stable prefixes, while others may change the prefix whenever the CER is reset." Feel free to offer up a better description. I think the salient point ends up being that the home network is going to have to be resilient to prefix change. > * Good text regarding PIA > * Regarding renumbering also note that operators take precautions to > ensure this is seamless as well including lease time lowering in advance > of the renumbering event.
