Here you are talking about 3ffe & arpa. I would like to know if there is something going to make reverse available for 2002::/16 addr space? Maybe there could be used automatic zone delegation by current ipv4 ns delegation?

Huh? 2002:: reverse delegation is available since 1999 or so, and since mid 2000 (if I remember correctly) both in ip6.int and ip6.arpa. That's not our problem here :-)

Sorry. I didn't have enough coffee yet. What I wrote relates to 2001:: delegation, not 2002::

The situation on 2002:: 6to4 space is still a bit unclear, at least in the RIPE land - there is an action item on the RIPE NCC to propose a solution for 6to4 RR, but as far as I know, nothing has been implemented yet.

This issue has been discussed at the private meeting during last IETF (please see David Kessen's report on this):

- 6to4 reverse delegation

We discussed this topic briefly as a lesser priority item.

As 6to4 is a transition mechanism for networks that can not get native access to v6, we concluded that reverse delegation might not be that important for the 6to4 addresses.

This is clearly a point for more discussion for the DNS wg.

We would like to get more input from the community with regards to importance of this issue and preferable solutions. Explicit delegation of NS records for 6to4 addressed may require quite a lot of coordination efforts and may not be the best solution as it comes from some IETF documents (for example draft-ietf-dnsop-ipv6-dns-issues-00.txt and draft-moore-6to4-dns-03.txt).
