Unfortunately, as long as the Feds have unhindered authority to force companies to do what they command, there will be no real way to stop their snooping. Think about an extreme example: the NSA gets a "court order" to force Symantec to open up a back door to allow them to put keylogger trojans on any machine they choose. At that point, no matter how secure a tunnel is through the internet, the NSA will always be able to gain access. So, you say: "Well Franken, your full of it! I have a SecureID fob, so my last password is irrelevant!" Then the NSA goes after the fob manufacturer to build in a mirrored fob to your own.
They can literally do anything NOT LIMITED TO the crowbar approach to password extraction. We should all be very afraid. This is way beyond overreach at this point.
