What's interesting is the NERC CIP push from federal to get power distribution devices onto a common IP network. I'm a bit fuzzy on the details, but there are major incentives and/or regulations to doing this, and it's a pretty important inflection point for the technology used in power companies. Even then, there are only a handful of companies playing in that space (Ruggedcom, Siemens, Cisco, some other traditional manufacturing PLC folks).

From my experience most of these devices are read-only monitors, but I'm sure there are exceptions. This little issue could be a big deal for their certification. I'm surprised they didn't take it more seriously. This is the hackers-will-take-over-our-power-grid kind of scenario the public doesn't like to think about.
