The Open Source enables you to migrate towards a free software, but there is
no chance to join your PC to the rest of the world in a free way.  
Imagine to be titular of full membership into a global Network, without signing 
contracts with any Internet Operators. Imagine to surf in a Net where there is 
no central regulating Authority which assigns conditions, names and suffixes...
Netsukuku, an Open Source software, which can be downloaded from
http://netsukuku.freaknet.org, makes possible the creation of a new distributed
global Net, expandable to an unlimited number of users, indipendent and
totally apart from the Internet.  Due to the Netsukuku particular routing
system, created by the "Freaknet" group of Catania (Italy), the Net is self
sustained, thanks to all the Net users, which share a small part of their
own PC resources.  Anybody has the chance to join the Net and, at the same
time, to make it grow.  The countries and areas of the globe where Internet
facilities are still not available, in this way and simply through the use 
of a wi-fi cover, can create and develop a Net without submitting themself 
to the Internet Operators or to its regulating central Authorities.
"You may say I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will be as one...."
