During the WG session, I kept notes about some issues that we might want
to track (on list or in the tracker -- I'll leave it up to the
continuing chairs to decide how). They are:

- delay is not *constant* on the Internet
- add reference to ITU G.107 regarding echo
- better explain echo and algorithmic delay < 10ms
- avoid phrasing subjective comparision in relation to ITU codecs
- clarify whether each requirement is nice or necessary
- clarify the measurability of each requirement
- clarify requirement about bit-exactness
- mention DTMF in requirements
- mention synchronization of audio with other media

If I missed anything, post to the list.

Peter
