Thanks, I hope they don't do it. I would expect the security community to be able to find something like this, since it's not hard to hook up some devices and do packet sniffing to detect if they're talking to each other.
This would be an excellent use case for LTT's faraday cage room for instance.
Thanks! As far as I know I'm not describing anything too unusual with the mixed-up signals, I think pins & needles is essentially that, just a bunch of nerves randomly firing, so you probably do know what it's like in little doses.
I've been paying attention to it since I wrote that, and it definitely is still slightly more numb on the affected side, I think I was right that not all the nerves regrew completely.
