Ned,

I am afraid I didn't explain my self well. I apologize.

I didn't mean to imply that the draft should be submitted as part of the
VPIM charter, nor did I say that it is should not be part of the Lemonade
charter.

All I was trying to do is open a technical discussion on the way SNAP should
be modified technically - not process-wide.

Noam

That's not how the process works. The process is that the group can forward
the document to the AD in change -- me -- and if I approve of it it will
then go to the IESG. And let me say right now that there's absolutely no way
I would sign off on this document coming from VPIM. And even if I did sign
off, I view the chances of this document being approved by the IESG in its
present form as nonexistant.

Exactly. Additionally, the document is listed as work item for the proposed
LEMONADE working group. Nor does this work appear as a deliverable for VPIM.
While the technical issues are substantive, so are the process ones.

I doubt very very much that this is the case. Even if you were to address
the outstanding technical issues by reducing the scope -- something I am far
from convinced is possible -- there's still the process issue to be dealt
with. Like it or not, this topic has been proposed as a work item for a new
working group. That alone argues quite forcefully for not trying to shortcut
the process.
