I request that you reserve time on the AVWG agenda to present the results
of your study group meeting and to discuss the technical and standards
issues in general.
I know there is interest in the TA in this general area (particularly the
isochronous part) and your study group meeting in T10 followed by a report
to the AVWG could spur an offline meeting in Seattle to talk about what
work is needed, how, when and where is the most appropriate way to get the
work done, and how to coordinate the possibly multiple foci of activities
