Box model / render tee

I was wondering if anyone from or who follows CSSWG who attended the talks
about the discussion on this topic that took place at the Extensible Web
Summit could share any of those discussions back with the group.  Due to
competing sessions i was unable to attend this one.  The minutes are
available @ http://oksoclap.com/p/P3aS4GtR2L - I'm wondering if there was
anything specific/useful that came out of it in terms of something the WG
is willing to take up?
