Hi All, I was unclear. I meant "Chairs, would you like to reserve a slot in the agenda so Lou and I can have a discussion at the mic about this topic, or would you rather we kept this to the list." If you do not have space in the agenda, I am happy to find a quiet spot and let everyone know so we can have a DLEP-DiffServ BoF.
