During the rest of the flight I wrote PySkyWiFi. PySkyWiFi is a highly simplified version of the TCP/IP protocol that squeezes whole HTTP requests through an airmiles account, out of the plane, and down to a computer connected to the internet on the ground. A daemon running on this ground computer makes the HTTP requests for me, and then finally squeezes the completed HTTP responses back through my airmiles account, up to me on my plane.

Huh. I guess… you could?
