Just wanted to report how the new Raspberry Pi 3 runs PirateBox.
The prebuilt image for Pi 2 doesn't work (the act LED blinks repeatedly, with a pattern of 8 blinks and a pause), so I tried the manual instructions on the latest Raspbian Jessie Minimal, and it worked fine. I was able to complete the entire guide with no problems. The PirateBox detected the new built-in WiFi chip, and hosted an access point. My only complaint is that it takes a long time for my devices to obtain an IP address, but that is probably just the devices themselves.
