I'd like to see the following moved to the first day as they are most important 

Error handling - how are we going to do this in general 

Stats - we need to deal with things like is this flat or nested and how we are going to do it 

Constraints - we need to nail this down and make sure we all agree on how it is going to work. Particularly how they are changed later on 

Permissions and privacy - this is still pretty hand wavy and going to be holding up implementations real soon now 

The sequence of how operation, particularly callbacks happen - I think this is in the sequence diagram reviews mentioned but we to get crisp on this. A key point that needs to be resolved is when a peer receives an offer, how it can tell what's in it before deciding to accept or reject it.

All the stuff here we have agreed to do in previous meetings and is trivial once we get the constrains stuff sorted out. I think this section could be reduce to about 15 minutes.

uh, sort of doubt any of this leads to anything that is not already in progress at IETF

The above point is addressed in the specs. Glad to clarify if there is a problem. The rest of the points are pretty vacuous and as far as I can tell more related to IETF work that W3C. If we can get some specific things that are W3C issues, sure but as this stands it's just more lets explode stuff. I think this section should get a lot more specific about what problem it is trying to solve and should be pushed to last topic on last day.

This topic needs an hour

I'd guess this needs 30 minutes

We really need to nail this one down. Perhaps an hour?

Probably need 39 minutes to an hour for states.
