another great read Dan! thanks :) my only comment, for now: """ Five years ago, Kelly Ziegler calculated that patching a fully deployed Smart Grid would take an entire year to complete, largely because of the size of the per-node firmware relative to the available powerline bandwidth. """ this does not take into consideration the "truck roll" option. it's the network operator's worst nightmare; an option of last resort. the majority of smart grid devices i have analyzed contain both optical and higher speed radio interfaces which may be accessed by a technician on site or near by. much more expensive than the slow trickle broadcast, but to claim a critical fix could be deployed only via one method is a bit misleading. p.s. hacking these devices still an undiscovered country! has your local utility given you one yet? best regards,
