I don’t doubt that routine scans by government will be mandatory if they aren’t already.
SOmeone needs to create a heavy encryption version of Linux.
There are plenty of crypto options with Linux. You can encrypt your home partition, the whole drive, or you can have encrypted volumes with built in plausible deniablilty.

From a Linux Forum:
Using Cryptovault for Password

Here we go...it's TrueCrypt:
Encrypt volumes through a cross-platform GUI with TrueCrypt 5.0
*********************************EXCERPT***************************************
TrueCrypt can create a hidden encrypted volume inside a standard encrypted one. As it's impossible to know if a hidden volume exists (hidden volume data cannot be distinguished from the random data normally filling the free space of a standard encrypted volume), this option helps you in situations in which you may be forced to reveal your password. See also Plausible Deniability in the TrueCrypt documentation.
