My understanding is that Speex default value has already been approved
in changes to the System Information draft which were promised by
today from the new editor of that draft.  If I'm mistaken about that,
please let me know.  If there is any contention on this question, I
would ask that the chairs resolve it by polling.

I would also like to get a sense of the chairs as to whether it is
appropriate to specify System Information about the network device
that would allow developers and users to assess network quality
characteristics, and if there are any such characteristics which are
off limits.
