Benoît and I talked about this on our call today.  We feel that it is an inform 
LS and the WG is copied.  So, we were going to leave it up to those in the WG 
that might be interested to comment.  I do like the idea of forwarding to the 
Sec ADs if they haven’t seen this.

Subject: Re: New Liaison Statement, "LS on work progress on quantum key 
distribution network (QKDN) in SG11"

Does anyone see anything beyond us, maybe acknowledging the statement, and 
forwarding it to the Sec ADs, if they have not already received the statement?
