Egypt and Technology

It is interesting to have read that Egypt shut down the internet to deny protesters the ability to keep in communication through the use of the internet. This is something that the United States have debated in having as well, a kill switch that the President has in order to shut down the internet. I wonder what it would take to do that in the United States. I find it terrible that a president can have such power and that it was used in Egypt, especially in a time that many people see as a tyrannical power position by the president. Without getting into the politics of the matter, I still find the power that the government can have over such communication to be a huge issue. It also calls into question what other powers major corporations and governments can have over such a system that is widely used and a major form of communication if not THE most widely used medium for communicating with others, for political and non-political reasons.
