Not wanting to drift from the initial topic... I'll just confirm (for the
"privacy-concerned" ones, that read the above posted) that, that is indeed
true. And, I've known that for years, from the same source that I linked to,
when I quoted above some examples of "spychips".
"By April of 2001 it had been documented that Echelon was particularly
effective against cell phones, and had even been improved to the point where
it would recognize the unique sound made by each individual key on a computer
keyboard. This enabled the sound of keystrokes to be picked up remotely and
translated into text."
--- Michael C. Ruppert, in "Crossing the Rubicon: The Decline of the American
Empire at the End of the Age of Oil"
"Latest advances in listening technology mean that if a bug can be attached
to a computer keyboard it is possible to monitor exactly what is being keyed
in. Because every key on a computer has a unique sound when depressed, it's
simply a case of translating the clicks into words.
"The threat of this technology has led some internet banks to rely on a
degree of mouse movement."

That's why one should never type sensitive passwords near a phone. ;)
(And, not going through all the incredible methods of surveillance that I
know of...) The establishment can, indeed, really surveil you, if it wants
to... But, it's not a simple, or easy, thing to do, to a lot of people, at
the same times... So, we should never facilitate such surveillance, by using
software or hardware with surveillance features already included in it, or
that we suspect it to, and that transmits all that we do to Big Brother, all
the time. (Or, we should, at least, try to avoid that same software and
hardware, as much as possible.)
