While I might enjoy the convenience, the way I stock my fridge just isn't a constant datapoint. If there are no eggs in my fridge, it might be because I don't want any eggs for a while, not because I didn't think of buying any. To solve this, you'd need human interaction etc. etc. and you soon arrive at a point where you just stock the frigging thing yourself anyhow. For a one-household effort, this really doesn't warrant the effort. A different story could be approaching it as some sort of communal effort, say the combined amount of fridges in one multi-story house or student dorm. If you could plan your meals /assisted/ by your fridge and it could tell you that the guy next door has eggs that are free, you wouldn't need to buy a whole carton just because you want to bake a cake, thus possibly reducing waste. In the end, this puts us back to the old privacy implications versus efficiency problem that remains largely unsolved.
