If this comment is interesting to you, you must read Mother Earth, Motherboard [1]. It's a fantastic long technojournalist piece by Neal Stephenson dealing with transoceanic cables.
In a nicely Pharaonic touch, one of the six ducts going
into the ground here is the sole property of President
Hosni Mubarak, or (presumably) whoever succeeds him as
head of state. It is hard to envision why a head of state
would want or need his own private tube full of air running
underneath the Sahara. The obvious guess is that the duct
might be used to create a secure communications system,
independent of the civilian and military systems (the
Egyptian military will own one of the six ducts, and ARENTO
will own three). This, in and of itself, says something
about the relationship between the military and the
government in Egypt.
If you have StyleBot, this makes it a lot more readable:
