RPUpi moved to the new RPUlux^2 and put a RPUadpt^5 on the PUlux^1.

The Pi Zero has a WiFi dongle so I can SSH into it remotely. The RPUbus goes over the ubiquitous CAT5 cable wired for ethernet (not the crossover variant).

Headless computers are a paradigm shift, I worry about how I will fix it if something goes wrong, but after switching from Raspbian Jessie to Stretch by way of a clean install I guess in the worst case it is easy enough to sanitize.

Notes firmware could be written to shutdown the battery backed Pi if the power is out for an extended period. The Wifi and network services (DHCP,DNS Host Mapping) also need to be battery backed for a laptop to be able to access them.
