internet - Is taming the internet possible?

Howard French uses in the New York Times the upcoming NPC to review China's measures to censor the internet. He seems to stick to the viewpoint that it actually works and uses the silence in cyberspace after Zhao Ziyang's death as evidence. I still wonder whether it is just traditional policing or sophisticated software that is doing the job. I go for the traditional policing.
Some of his evidence sounds utterly unconvincing.

According to Amnesty International, arrests for the dissemination of information
or beliefs via the Internet have been increasing rapidly in China, snaring students, political dissidents and practitioners of the banned spiritual movement Falun Gong, but also many writers, lawyers, teachers and ordinary workers.

Names and addresses would be useful here, since I have personally not that many examples at hand. I was asked by a new committee for the protection of bloggers for those examples, but they had to rely on Iran to find arrested bloggers. What is happening is that some people who had already a reputation for getting into trouble now include the internet in the ways to tell about their viewpoint.
I would rather stick with Guo Liang, who is only quoted at the end of the article, while I think his message is crucial:

"All of the big mistakes made in China since 1949 have had to do with a lack of information," said Guo Liang, an Internet expert at the Chinese Academy of Social Sciences in Beijing. "Lower levels of government have come to understand this, and I believe that since the SARS epidemic, upper levels may be beginning to understand this, too."
The most eagerly watched key word in China today is probably Falun Gong. "I don't know the number, but I would guess every Chinese has received a Falun Gong e-mail," Mr. Guo said. "There is no way to stop it. You can shut down the Web site, but you cannot kill the users. They just go somewhere else online, sometimes keeping the same nickname."
