You can hook up to the houses with mirrors and QR protocol to the fiber optic cable down the street, but the total cost including repositioning the mirrors, cleaning the cameras, and powering both computers will be much higher than just branching from the nearby cable. | |

The QR codes will be a bottleneck for speed, because they can't send as much information as a fiber optic bundle of the same size... | |

In other words, just flash QR codes really fast. If a person can read it, so can a computer. Even high level of nonlinear displacement should be possible to compensate with enough AI - edges in QR codes can be used to register them onto a grid - or you can even devise a protocol that is unsusceptible to deformation. | |

The error frequency could actually be very high without people noticing. Even if all pixels are moved a little, the eye won't be sensitive enough to tell, but a computer will. | |

Given the advantages magic mirrors offer, even 50% loss in a 2-way connection could be an acceptable trade off for those advantages. | |
