Hey, it's all good. Once we've got fridges hooked up, coke cans and bottles, Lunchables, and every other food related item and cigarette packs, alcohol bottles, beer mugs, and so forth we can pass a law where they will integrate with our shiny Obamacare system so that your insurance can be adjusted according to what you eat! Perhaps all of our lives little details will become mandatorily given to the government for our own good - you been getting around a sleeping with some honeys (I know, this is Slashdot, but we can all have a dream!) , the government must know because it increases your risk of an STD which increases your risk profile, own a gun? that'll be hooked into the government information pool too. Own a gun? Watch too much TV? Play too many video games? Don't watch enough government sanctioned TV? Everything can be used to enhance your profile of insurance risk, terrorism risk, etc.
The third party doctrine will accommodate any invasion of privacy since, under current law, once information about you becomes available to a third party, the government can compel it's production without a warrant. Once everything you own is hooked up to the Net, it all becomes fair game for government analysis. Of course, once these functions become ubiquitous opting out will become impossible but the courts will continue to waive their collective hands and say that we willingly sent our private information to a third party so it's fair game for the government.
