I disagree. I look forward to a day when all home users by default
have a public IPv6 address for each of their machines and hopefully
enough to support multiple subnets within the home.

Until then, IPv4 service without at least one public IP is degraded
at best compared to what most people consider normal residential
internet access today (which, frankly, is degraded at best compared
to what I consider normal internet access).

You're not that atypical either, at least compared to US users. The
following very common applications are known to have problems
with LSN:
        Playstation Network
        X-Box Live
        AIM/iChat/FaceTime
        SIP/Vonage/other VoIP services
        The HTTPs Server on TiVO boxes
        Peer to Peer (torrent, etc.)

Other less common applications also have problems:
        HTTP servers
        SMTP servers
        Back to my Mac
        VNC
        Tunnels

While this is true, I'm not sure it's all that relevant.

Most ISPs I have talked to in the US are dreading the deployment
of LSN and not planning to deploy it by default except to the
extent absolutely necessary to meet customer demand.

Moving them to IPv6 and hoping that enough of the content providers
move forward fast enough to minimize the extent of the LSN deployment
required.
