I spoke online to a child porn collector who claimed to use a similar system to obtain cp. He'd buy used laptops for close to nothing and place them to leech off public WiFi. They had anti-tamper systems, although he wouldn't reveal the details. (He ditched them aggressively at the slightest sign of trouble). The difference was that he connected to the laptop via the same WiFi the laptop leeches off, thus giving less additional protection than the radio hop.
