Thanks for your report. It's currently the MPEG meeting so I'll give
more detailed comments ASAP. Still, I do not see mentionned the report
on the Web/TV/MPEG-4 discussion we had. Was there a misunderstanding ?
Should Rob and I have to provide you something that we failed to give
you on time for your report ? Please, tell us, we will send this
info. ASAP in order to complete your report on this key issue.

Besides the usual blabla, one important decision which was  took was to set up
a joint reflector with a precise mandate (to be refined ;-).

See you,

Olivier
