Something like ladyada's Tweet-a-Watt? (http://www.ladyada.net/make/tweetawatt/). Device level monitoring makes so much more sense! Especially when a utility provides variable pricing for the electricity. For example, an monitoring unit built into the dishwasher would be able to turn on the appliance when the electricity demand is low and hence the kWh cost is low. But yes, it's a good starting point for Wattvision. Their future releases will probably be smarter and richer in features.
