Thanks a lot for this update, it is most interesting. Reading through it I find that most of my comments are of a rather editorial nature, and as such I will get back to them later. Most importantly I find that this draft is much clearer and presents a better defined approach to the problem.

I agree that this would be a good path to follow. The first step is to give it a home in CVS. I believe that you already have an account on dev.w3, so the simplest thing is probably that you add a "powerbox" directory to http://dev.w3.org/2009/dap/ and place it there. The next step would be to agree on what makes the draft "good enough" for a First Public WD. Apart from general consideration about quality and pubrules which you already know and which I'm not worried about, a general rule of thumb which we use in this WG is that ideally a FPWD ought to be roughly and to the best of one's guesses feature-complete (though of course it doesn't need to be perfect :) The reason for this is that it provides somewhat better protection against IP issues for everyone. If you think we're roughly there, then we can issue a call for consensus to publish the document. We'll deal with the delicious vagaries of Rec-track life afterwards.

Process question for Dom: do editors listed on a draft have to be formally members of the WG? The companies listed already are, so my understanding is that we're covered IP-wise.

To make sure that everything is in the clear, at the last F2F the group agreed on what we call informally "the Prague Doctrine"[0], which is essentially that we didn't want to pre-emptively decide between tradition/JS/host object and REST/Powerbox implementations. This means that we endeavour to produce APIs that can be bound to both views, but that WG doesn't wish to dedicate a lot of bandwidth to the wiring of those bindings (since this essentially means not spending a lot of telecon time on them, I doubt it will prove to be an issue though). As part of this decision I've offered to create a REST/JSON binding for WebIDL so that the mapping would be consistent. To date this has essentially been about me scribbling stuff down and tossing it into the trashcan but I might have a new take  either way suggestions welcome!

Note that if other editors need access to CVS, they should email Dom offlist with their SSH pubkey (and CC me).

Thanks a lot!
