Francois,
 
The bi-directional TCP support was added during the last Geneva meeting.  No issues were raised in Osaka.  If there are issues with it, hopefully people will find them before November!
 
We could specify that H.323 use H.245v7-- I do not see any reason why we should not consider that option.  The only reason that I did not increase the revision number is that Annex D may be implemented optionally.  If somebody chooses to implement H.323v4 without Annex D support, there is nothing they would need from H.245v7. 
I have no problem with mandating v7 for H.323v4. It is a small editorial change: a "7" instead of a "6" ;^)
However, it really makes no difference at all to me.  I'll be agreeable with whatever the experts believes makes the most sense.
Me too.
