Imagine if this hack was done to the countless number of redundant satellite dishes in Cairo. At least two dishes will be needed on every building communicating with other dishes on neighboring roofs in a mesh network. Instant free (or extremely inexpensive) connectivity for everyone. But illegal of course.

And, according to this we can point all those satellite dishes to the heavens and connect them and create the largest radio telescope ever! It will make mockery of the Very Large Array. A radio telescope with the diameter of Cairo! But people want to watch Hayfa not pulsars, of course.
