6to4 does exist on Mac OS X 10.2. It just isn't integrated in to the 
user interface. If you run the command line (Terminal application), you 
can use the script ip6config to turn on 6to4 (i.e. sudo ip6config 
start-stf en0). 10.2 also comes with rtadvd for advertising routes. 
IPv6 support is in 10.2, it's just isn't available through the user 
interface.
