I think what you'd be doing is giving anybody you have assigned an IPv6 =
address to the ability to update the PTR (or a delegation, since Mark =
suggested that too) for that particular address.
So, it's not "my reverse delegation", it's "my 2^80 or fewer reverse =
delegations" (if you've been assigned a /48).
