Interestingly enough when I worked at Fujitsu in 1999/2000 they had a concept of an e-fridge and I believe they had a working prototype. It had a barcode scanner and a network jack and you would scan stuff as it went in and scanned it when it was empty. That way you kept track of stuff.
LG makes one similar - tied into a grocery service, even, so you can make a shopping list or order stuff straight from the touch screen on the door... I helped install a bunch of them in a high-end condo development a friend of mine worked on.
