Here is one small example: In Feb 2007, M$ with the help of local police started raiding on different places in West Bengal for pirated windows. As they came to Durgapur (Dist Burdwan), the local cybercafe owners were too tensed , some of them closed their shops until those people went back. But some others chose GNU/Linux right away. Our LUG members installed GNU/Linux in few of the cafes , where in some they installed themselves. And they are happy with it, they don't want to go back to windows any more.
Great job! Keep it up.
That means it can be done in a larger scale.
For that you need people who have the ability to dream, instead of laughing at them. :-)
Happy hacking, Debarshi
