Yes, Thank you Koen for all the work I'm sure you must have had to put 
in to making this happen. We can now focus solely on technical matters.

As regards the remaining patent family no longer owned/controlled by Nokia or Alcatel Lucent, we understand that this is directed to an optional and not recommended part of the IETF draft.
