I am interested to hear how receptive and supportive your neighbors end up being to whatever you present to them-if your arguments work to convince them to be opposed to smart meters.
I have heard about ICEblock. I like it in theory but I have my concerns.
Another thing just came to mind due to your ICE related comment. The smart meter information may be used to track how many people are actually in the residence. Changes in usage patterns can be recognized more readily. One protest sign I saw stated something to the extent that they were protesting because it was easier than hiding people in their attic. The kinds of granular data collected on usage combined with information known about demographics I can see being used to identify where people may be hiding which could be turned over to whatever agency that might benefit from having that information.
