Next f2f and charter issues

At some point, it would be good to discuss what this working group is
expected to look like next year.

Specifically, are we planning further f2f meetings? Some people need to
budget for this, either financially or in terms of time. Similarly, the
current charter expires in January 2013. The group got an extension last
time the charter was near expiration, and we did not object formally, but
did raise some concerns offline. While we're trying to move towards
decisions on some of the open issues, I think it's safe to say there's
still a fair amount of skepticism around whether we're getting closer to
producing a document that's actually going to be acceptable to enough
parties that it receives wide implementation. I'd like to have a discussion
on scope and figuring out how we can try to ensure some sort of successful
outcome (whatever that may look like, perhaps a narrowed focus on the
technical side of things / TPE) and actually discuss this as a W.G., rather
than just another extension without working group discussion.
