There ARE options for power regulation that aren't terribly expensive. This is an issue for automobiles where someone has installed a Linux computer off the cigarette lighter (which is switched on/off by the ignition). Here is one example, I've seen other fancier ones for more money: https://www.pi-supply.com/product/pi-ups-uninterrupted-power-supply-raspberr...

After all the comments, here's how I see this working: connect the Pi (or
any appropriate microcontroller) to the TV via HDMI so we can get power from the USB port. There aren't outlets in the ceiling/attack and it would save us money on cabling. Then use WiFi or Bluetooth to wirelessly connect the Pi(s) to our network.
Then where do you plug in the TV, if there's only a single outlet, couldn't you add a multi outlet adapter, to give you 3 outlets It's not safe to power off without a shutdown on the RPi, if the TV's usb port shuts off, just as with any Linux system. People do it anyway, when they unplug the adapter on the RPi, but they are just lucky till their SD card get scrogged Dan
Dan it can be done, if we can setup the SD read only, turn off swap and any application that write to the SD (such as syslog). When we need to write the SD (for configuration) we can remount the SD as write.
