Oh, - here's my short speech on privacy at the 2010 SCALE 8x Linux Expo
in Los Angeles this last weekend.

A quick comment about Thomas Landamann's tagline from another thread...

Uh...
Liberty is what a sailor gets for a while when a ship gets into port - a
temporary leave of absence.
3. A privilege conferred by a superior power; permission
granted; leave; as, liberty given to a child to play, or
to a witness to leave a court, and the like.
[1913 Webster]
Freedom - now that's what you mean to say. I am the superior power. I
need no man to confer privileges to me.
Democracy is mob rule - ancient brutality. Add to the conversation that
no man can be sure his mind hasn't been tampered with by electronic mind
control techniques to apply coercion, undue influence, fraud or
subliminal influences and you suddenly have a difficult time proposing
any government style that offers any legitimacy. See project "Commander
Solo" and you will know why voting is an illegitimate means to
determine anything anymore.
The civil thing is to allow any one man or woman to veto everything.
Unanimous consent - voluntary participation.

David Sugar is a developer in the GNU Telephony project and he invited
me to speak on the importance of privacy during his speech. David is
also an international ambassador for the Lakota Nation.
His program Sipwitch is in use by many embassies around the world to
implement secure telephone communications with gnu software inspired by
Phill Zimmerman's zrtp protocol. He wishes everyone would use
I learned something about Gnu ZRTP - it is a zero knowledge protocol. A
person need not have any knowledge of the passphrase of any key to use
it and for every conversation a new set of keys can be used. This is
actually quite important so that one cannot be forced to give a password
that gives access to the key that would unlock the contents of a
conversation.
And here's why ZRTP is so much better than any VPN system....
You can call any other zrtp enabled sip client without having to
engineer a vpn ahead of time. So any embassy can call any other embassy.
Here's some more info about GNU ZRTP :
