Depends. What servers do you connect to most of the time? If they are local to the Chicago PoP, your connection might be better than having a Chinese PoP which might have bad connectivity to the US. Why Blasphemy? Hexago, which is now GoGo6 sprouted from Viagenie. Viagenie are the folks who setup the first Tunnel Broker: Freenet6. And with that they helped a lot of people get IPv6 connectivity, which is the same goal that SixXS has. Absolutely nothing wrong with that. As for their "on demand" part, that does not really help if you only have a box in Jakarta, Amsterdam and Montreal and all in the same IPv6 /32. They also seem to have a lot of connectivity issues because of their attempt to only announce /39s, which does not work. Note that TIC can also do anonymous tunnels and can give out tunnels on demand, there just is too much abuse to enable that. When people know that their details are available and that their actions can be easily traced to them, they tend to abuse a lot less, which means the more time we have left in our precious spare time to actually help people do something useful with IPv6. If you want a truly mobile IPv6 address look into Mobile IPv6, it was made for it, but indeed requires that there is proper IPv6 everywhere. Otherwise Teredo and 6to4 might serve some purpose. Native IPv6 connectivity is the true solution though. When you request a tunnel here, that is also one of the many factors that the tunnel approval is based on. You just need way more PoPs to cover the globe. And unfortunately there has not been an ISP from the Asian region yet.
