If the Chinese keep policing the internet in their country like they are now, there may not be much of a future for them, or .cn's.
They frequently shut down any sites with violence, sex, or anything remotely against China. Not exactly free speech over there. They could just as easily take a domain from you.

This was taken from it:
China's laws require Internet service providers to keep detailed records on everyone who uses their services, and to provide that information to public security forces upon request.
People who post content critical of the state or of Communist Party officials have frequently been detained and sometimes sentenced to long jail terms. A recent case was that of dissident Shi Tao, sentenced to 10 years in prison in April after Yahoo's Hong Kong office provided his IP address to public security agents.
Don't get me wrong, I'm all for country codes... I just thought this was interesting and should be considered.
