Can you please elaborate how this will work?
Will it require collaboration from the IPv4 upstream provider?
(i.e. will the delegation under the  2.0.0.2.ip6.arpa follow the same
path as under in-addr.arpa?
Another way to ask the question is where will 6to4 users have
to go to get reverse delegation? to their ISP or directly to the RIR?

How will it work when the IPv4 address is transient, i.e. DHCP allocated
for a short lease (typically less than a day)?

good point, I will add a section about this in the next revision.
