It is my understanding that you already plan to do that in -08.

That's very sensible but that doesn't mean it's going to happen.

Understood.

I think one has already been identified.  To make this scheme work, there
will need to have a common metadata format implemented.

Once it is implemented, it will need to be specified, leaving you with
following tasks:

   - Identifying a victim to provide it.
   - Figuring out when/where it will be provided.

The virtue of the IANA registry is that it gives you the ability to defer
these tasks.
