Sure, it's the flow labels and the ethertype that people find too  
difficult to deal with so they're not deploying IPv6.

Remind me, when were the DHCPv6 specs finished again?


The big thing in IPv6 is the larger address size. All the other stuff  
is certainly interesting and we can discuss it to death, but if and  
when desired, it can be bolted onto IPv4 and you can translate  
between the old and the new IPv4 so no deployability issues (well,  
except overzealous firewalls, of course). The part that requires  
upgrading ALL hosts and routers is the increased address size.
