Interesting, and I also own a nice size chunk of NIHK, Nighthawk Systems. You folks might want to check this companies products out. Their customer base is primarily utilities, with their remote disconnect unit for residential metering.

Having been in the electrical switchgear field for 40 years, this company caught my attention about 2 -3 years ago as a speculative buy. They closed just over a nickel on Fri in vol close to 900K.

Their no future EDIG IMO, but looks promising.
