This is good for monitoring single appliances, but it's a pain in the neck to keep moving it from appliance to appliance. Do you know of one that I can attach to my power meter and it'll give me realtime usage, tracking, reports so that I can see my peak, minimum and average draw for the whole house?

There's a product called the Efergy True Power meter that does exactly that. It measures mains electricity, wirelessly reports to a central server and shows you real time and historical graphs of energy usage at sub-minute resolution. http://efergy.com/us/elite-true-power-meter
