Towards the real deployment

Host OS, Router OS are all ready by now
*BSD, Solaris, Linux, whatever
Cisco, Juniper, Extreme, NEC, Fujitsu, whatever
It is just a matter of configuration to enable it

Most of applications are ready
Upgrade application, or library (if library API is address-family neutral)

Education is the key
Educate ISP operators
Educate university operators
Educate end users (may not be necessary, as IPv6 is hidden in the very bottom)

Server and client
We need to convince server operators - like yahoo
We need to convince customers - like DSL customers

Convince your boss, configure it and use it!
