Someday, I expect the pantry to have a barcode reader on it
a computer setup for the kitchen someday. Most of us already use
readers when we shop so its not a big step to home use.
Nah... That's short-term thinking. The future holds advanced
RFID sensors that know what is in the pantry and when they were
what their expiration date is, etc.
And since your can of creamed corn is globally addressable, the rest
of the world knows what's in your pantry too. ;)
This definitely helps explain your misconceptions about NAT as a
Globally addressable != globally reachable.
Things can have global addresses without having global reachability.
these tools called access control lists and routing policies. Perhaps
of them. They can be quite useful.
And your average home user, whose WiFi network is an open network named
"linksys" is going to do that how?
Because the routers that come on pantries and refrigerators will probably be
made by people smarter than the folks at Linksys?
I respectfully disagree. If appliance manufacturers jump on the bandwagon to make their device *Internet Ready!* we'll
see appliance makers who have way less networking experience than Linksys/Cisco getting into the fray. I highly doubt
the pontifications of these Good Morning America technology gurus who predict all these changes are coming to the home.
Do we really think appliance manufacturers are going to agree on standards for keeping track of how much milk is in the
fridge, especially as not just manufacturing but also engineering is moving to countries like China? How about the
predictions that have been around for years about appliances which will alert the manufacturer about impending failure
so they can call you and you can schedule the repair before there's a breakdown? Remember that one? We don't even have
an "appliance about to break, call repairman" idiot light on appliances yet.
But I predict the coming of IPv6 to the home in a big way will have unintended consequences.
I think the big shock for home users regarding IPv6 will be suddenly having their IPv4 NAT firewall being gone and all
their devices being exposed naked to everyone on the internet. Suddenly all their security shortcomings (no passwords,
"password" for the password etc) are going to have catastrophic consequences. I foresee an exponential leap in the
number of hacks of consumer devices which will have repercussions well beyond their local network. In my opinion that's
going to be the biggest problem with IPv6, not all the concerns about the inner workings of the protocols. I'm guessing
the manufacturers of consumer grade networkable devices are still thinking about security as it applies to LANs with
rfc 1918 address space behind a firewall and haven't rethought security as it applies to IPv6.
