I wonder if there's a simile to make with electric utilities. A "smart grid" could potentially distinguish between surcharge-able electrons, just as a "smart internet" (one without net neurtrality) could distinguish between good and bad packets. Would you want an electric utility to be able to charge you more because you bought the wrong brand of refrigerator? Or were charging an imported electric car? Of course utilities will charge more for peak hour usage right now, but at least every electron is charged the same at that time. What do you think?
