Completely agree. NRENs are in the group of ISPs with more IPv6 
experience. And, it is a fact that this helped vendors to tackle 
problems. Also, given that NRENs are quite different in topology and 
equipment, their experience will for sure be benefitial as an example on 
how to deploy IPv6 for other ISPs...
