> I'd like to get a series of software upgrades so that my connection works with ipv6.google.com. Yeah, I know - I can't get that.
Actually, you can. If someone made a software upgrade which installed and enabled teredo (which needs no configuration to work), your connection would work with ipv6.google.com. On Windows, there is no need to install teredo at all, just enable it - and I heard some Bittorrent clients did enable it for you automatically. And teredo works perfectly with ipv6.google.com.
