It says the US should pay $250/tonne of CO2. I'm sure this would be high enough to change behaviour, but imagine the political system capable of putting this in place. I think subsidising renewables and CCS directly to try to make them cheaper than (unabated) fossil fuels, with a lower carbon tax, is more likely to work.
If I decided to do this, I would need to operate my LAN like every node was bare on the internet. I've got fileservers with guest access (for, you know... houseguests), web services, my invoicing system, and a whole slew of other personal services. The thought of open wifi on the LAN kinda scares me from a security perspective.
