I don't see how this proposal solves problems 1 or 4 above, though I'll 
grant it may partially solve problems 2 and 3.  I am particularly opposed to 
abusing the 6to4 spec in this way; if a change to 6to4 is desired (i.e. 
leaking routes under 2002::/16 into the DFZ), then the IETF is the proper 
forum to do so, and ARIN should not be considering policy that depends on an 
RFC change until a draft is at least in the RFC Editor's queue.

If the goal is to give PIv6 space to legacy holders -- without meeting the 
existing standard -- in return for subjecting themselves to the RSA and 
maintenance fees, then I feel that the appropriate place to propose such a 
change is in the PIv6 policy itself and that such blocks should be assigned 
from the same superblock that other PIv6 space is assigned from, not from 
2002::/16.
