DNS A6 chains

[JOIN Project Team]

I want to setup A6 chains for us and our leaf sites. I was wondering 
if the 6bone's nameserver is capable of resolving A6 records, so I could 
add a proper referral to 6bone.net or somewhere else? Something like this:

$ORIGIN ip6.join.uni-muenster.de 
leafsite0100    IN      A6      24      0:0:100::       join.ip6.6bone.net.

,while 6bone's nameserver would respond with the first 24 bit of JOIN's
assigned prefix 3ffe:400:: if queried for join.ip6.6bone.net. 

Are such references possible now or in the near future? 

Thanks,
    Christian
