So in China, Iran et al., you can get past censorship with VPNs. If I understand this correctly, China&#x27;s GFW blocks about maybe 20% of the internet, while Facebook&#x27;s proposed free ISP blocks perhaps 90%.<p>Perhaps there&#x27;s room within the remaining 10% to create a VPN and fudge access to the free internet? Perhaps using TCP-over-DNS, or even something ridiculous like TCP-over-Facebook-chat?
