As this was partially addressed to me I'll make a brief reply. However, for 
a more informative answer, others on the 6bone list will have to respond.

It is the intent for IPv6 hosts/networks to progressively switch to new 
versions of DNS that support A6 and DNAME records, when they are well 
developed, tested and widely available. I don't really know the current 
status of this, nor the answer to your two numbered questions, thus I must 
leave it to others on the list to respond. Let's see what they say.
