Seems like it'll be very hard to block, except through agreements between China
and those web content delivery networks to serve different versions (or not
serve it at all) based on the geolocation of the IP address. China might not be
able to convince companies to do this based on censorship, but it may become a
semi-standard practice to customize web content and auto adjust languages. Some
sites already do this, I believe.

By exploiting the plumbing of the Web, researchers have created a new way
around online censorship that governments could struggle to shut down.

The most established tools for avoiding Web censorship rely on computers
located outside a country that censors the Web. Those computers must access
pages on your behalf and relay the data back. Tor does that using a network
of computers offered up by volunteers around the globe. Using a VPN
connection has a computer pull all its traffic through a particular computer
rented out for that purpose.

CacheBrowser instead exploits a mechanism used by companies to make their
pages load faster to allow a computer to sidestep the censors and access the
pages it wants directly.

Censorship systems like China’s mostly rely on blocking computers from
accessing the Web addresses and IP addresses, which identify specific
servers, of blacklisted sites. But when you visit a popular website, your
computer is usually directed to download it from the servers of a content
delivery network, a company such as Akamai that website operators pay to
store copies of their data on many servers around the world so people can
access it faster. Use of content delivery networks is very common among major
sites and growing; Cisco expects a majority of all Internet traffic to pass
through them within a few years.

Censors tend to leave content delivery networks alone because their servers
host many different sites, most of which they don’t want to block, says
Houmansadr. CacheBrowser works by going directly to content delivery network
servers to download pages when you type in a Web address, using a lookup
table of websites and their content delivery networks.

If Cisco will be capturing and handling the majority of Internet traffic,
what is their true role in the growing global 'security' grid? Are they the
noble guardians of the 4th and 5th Amendments (or their equivalents)?

What percentage of Cisco is owned by the Chinese (or one of their surrogates)?

How many Chinese work for Cisco?

How many offices does Cisco have in China (Shenzhen, Hong Kong, and
