This fairly accurately describes the current IPv6 situation. For his specific points: * Hardware: this is a huge problem. Apple's routers support IPv6 just fine, but most of the other stuff is a mess. D-Link supports it in some revisions of some of their routers, but even then doesn't support IPv6 firewalling, opening up your whole network to the public * Sites not working / testing: Facebook and others are currently pretty busy with testing IPv6. This unfortunately means that sometimes you'll get failures, like with the bit.ly. The Facebook thing is still only a test setup, which you explicitly use yourself, so you'll see issues there too * Privacy: While it's a bit of a concern in some current implementations, everybody is moving towards enabling Privacy Extensions by default, which should mitigate this. Using your MAC address as a public identifier is IMHO a dumb idea, as you'll be able to be tracked across networks, people can determine what kind of hardware you're using, and it works for protocols outside of HTTP too (as you don't require cookies). So, while the current situation is bumpy, I think this is a sign that people are actually working on IPv6 to implement it and improve it, rather than ignoring the IPv4 exhaustion altogether, so I guess it's a good sign.
