Amazingly still not going dark...
Some years ago I noted how easy it was to wirelessly link up two laptops while connecting one to the wired network. If I could do it across a room, it could be done between the building and a car parked outside. We've also had plenty of "stupid luser" tales where a rogue wireless network appeared in an installation because some sales droids snuck in a router. Wireless networks = zero security.
And yet, probably because of expense and the fact that it would rob the suits of their ability to stream pr0n on their phones, buildings are not going in for EM shielding, even at the room level. It's not enough to secure your own stuff, you have to prevent any other stuff from running inside your "secure" zone. Whether you're running a brokerage or a prison, smuggled in wireless equipment is going to destroy your security.
There will probably be a massive incident sooner or later that will set the trend to turn buildings into Faraday cages. Then there'll be laser links, so goodbye windows....
