I see this as a business opportunity for competitors of US companies
to host their servers outside the US juristical access.
And implementing a strict secure communication from client to server (https for starters)
At one time there will be economic pressure to reduce (or make people belive so) the
sniffing on their private communications.
The main effect of observing and recording peoples behavior lies less in aquiering intelligence data to find bad terrorists
(or drug trading, or tax fraud, or pirating software, or mobbing schoolmates, or throwing away beer cans on the highway, or critizising the current govenment)
But more into making people change their behavior in their daily lives. (a broad feeling of intimmidation)
Beeing more careful and communicating less critical.
