The Question Box is a simple telephone intercom. Its purpose is to connect people to the Internet. It requires no literacy or computer skills.
Users place a free call by pushing the green button. They connect to an operator sitting in front of an Internet-enabled computer.
Users ask the operator questions. The operator goes online and finds their answers, translating them into the local language. The operator also sends & receives emails on the caller's behalf.
Juicy job for the village gossip.
To make this work for anything other than generic information retrieval (and not force the user to share credentials), you'd want to allow the user to grant constrained access tokens to the (hopefully bonded) operator.
