The way your first paragraph is worded reminds me of this Obama-using-a-blackberry stuff that is making the rounds. There are other risks than the receiving end in the president's case. When it's easier to communicate, via any available channel, the ability to access the communication channel ceases to be a decent (reliable?) authentication mechanism. Movies always seem to get this wrong, in both directions. I mean, did Trinity REALLY have to physically break in to the power plant to use an ssh exploit? If she could break in, why was an ssh exploit necessary. And if she could use an ssh exploit, why did physical access help? It all seems unlikely (but makes for good explosions).
