As I mentioned on the call, there are 3 main reasons for listing items 
as out of scope:

1) To set expectations and forestall off-topic conversations that 
prevent the group from making progress, when the item might otherwise be 
expected to be discussed;

2) To prevent overlap with work from other groups; and

3) To delimit issues that have potential IP concerns, to increase the 
possible participation by companies that may have reservations about 
joining otherwise.

Given Noah's concern about the implications of putting streaming out of 
scope, I would like to either define better what is meant by it (similar 
to your explanation here), or to remove the passage putting it out of 
scope.  Without knowing the rationale for putting it out of scope, I 
don't know which to do.

If anyone has improved wording for the charter here, or can share the 
rationale with me (onlist or offlist), that would help me in finalizing 
the draft charter.
