Could a snailmail/sneakernet gateway to the Web be implemented for prisoners? Email/telnet WWW gateways were used in the early days for people who couldn't install clients, were on intermittent connectivity, etc. I must admit to fantasising about truckloads of paper rolling in and out of prisons until somebody says "Enough" and gives them Internet access. The carrier pigeon RFCs could actually be put in to practice here, just think of the potential.
