A quick response from me: I think in general terms this is a good approach - if all the EPDP members enter into it in the right spirit.
In terms of deference to the small groups - I think a key to success is that small groups must be clever enough to recognize and flag anything controversial enough to require consideration by the plenary. Just as we don't want the plenary to relitigate what the small groups do, we also don't want the small groups to pre-empt decisions that should be made by the plenary. In case of doubt, kick it upstairs to the plenary. Otherwise we WILL end up re-litigating a lot of things.
I agree with your categorization of the purposes, but haven't had time to review how you categorized all the recommendations. I'll do that as soon as I can. If you don't hear from me by end Sunday (Monday morning for some of you) I have no objection.
