Graham and all,
I am providing a summary of the current position and feedback.
This will be points that we try to get agreement on.
1. endpoint-user must be able to access OPES diagnostic
   information using legacy s/w.
2. have no problem with protocol extensions being available to
   facilitate access to the information.
3. not opposed to using In-band information even if it means extensions
4. keeping a log could be quite sufficient
5. having out of band access from one endpoint or the other is a far better
   outcome than having none
6. (From mark baker) No need to standardize on a callout protocol.
Here I propose that we start a new thread where each point is 
discussed and get solved.

Unless I've missed something (which is certainly possible), the draft 
may want to suggest how the OPES architecture will respond to the 
following IAB consideration:
   (3.1) Notification: The overall OPES framework needs to assist
   content providers in detecting and responding to client-centric
   actions by OPES intermediaries that are deemed inappropriate by the
   content provider.
The response may be that this consideration will be addressed in a 
requirements document -- for example by requiring the initial request 
from a client to a content provider to deliver a header flagging the 
client-centric OPES action to be performed.  Although such a header 
may not have major "architectural" implications, in explaining and 
understanding an OPES flow it seems appropriate to state that there 
should be notice to the "other" primary party (i.e., the party not 
initially requesting the OPES transformation) of the planned OPES 
transformation or callout PRIOR to the transformation or callout 
actually happening.
A small and unrelated point about 3.4 of the draft:
3.4 Privacy
   Some data from data consumers is considered "private" or "sensitive",
   and OPES processors must both advise the primary parties of the their
   privacy policy and respect the policies of the primary parties.  The
   privacy information must be conveyed on a per-flow basis.
Especially as peer-to-peer technologies become more widely used, 
there will likely be times that data providers also have private or 
sensitive data. I suggest changing "data consumers is" to "data 
consumers or providers may be."
