find AAAA records is all that great.

At least eNom does.

There are a few others but it tends to be that you have to raise a
support ticket to actually get the records in, most webinterfaces don't
support it yet unfortunately.

One note here is that even though you can get glue into com/net/org
using this method, there is no IPv6 glue for the root yet, as such even
if you manage to get the IPv6 glue in, it won't accomplish much (except
sending all IPv6 capable resolvers over IPv6 transport :) as all
resolvers will still require IPv4 to reach the root. One can of course
create their own root hint zone and force bind, or other dns server, to
not fetch the hints from the real root, but that doesn't help for the
rest of the planet. (Root alternatives like orsn could fix that up but
apparently their main german box that was doing IPv6 is out of the air)

      You don't change the hints you just provide zones that override
      B.ROOT-SERVERS.NET, F.ROOT-SERVERS.NET, H.ROOT-SERVERS.NET,
      K.ROOT-SERVERS.NET and M.ROOT-SERVERS.NET or just use your
      own ROOT-SERVERS.NET zone with the AAAAs added in.

I've read your email twice and I dont follow. 

Either you are telling me

a) Provide my own hints with AAAA included (you specifically say thats not what you mean tho)

or

b) Serve my own root zone. From a root operator, surely thats not right either (I hope!)?

      In the few couple of years I've only seen two outages with the
      IPv6 root instances.  In both cases they were fixed soon after
      reporting the outage.

So there are v6 roots out there? Where are they hiding and why arent they being provided in the hints file or NS 
queries on . ?

Note also that various ccTLD's are able to add glue to your zone on
request (notably .fr/.ch/.nl/.se do so already for quite some time)
