Dear colleagues, Preparations already started for RIPE 66. Please take a moment of your time and help in this process by telling us which topics, technologies or speakers would you like to see in Dublin. Our working group is chartered to take on "anything useful in helping people to deploy IPv6, and to manage IPv4/IPv6 co-existence", why not write it in with that one question you would really like to get answered. As part of our two 90 minute slots, we are thinking of dedicating a portion to a measurements theme track. The questions we would like to ask there is where measurements become useful to your IPv6 deployment, or to rephrase, which measurements would you like to see? Help us shape the agenda by providing your feedback. Reply to the list and you may find yourself amongst likeminded people. Of course if you have this wonderful IPv6 project or idea you would like to share, we are always open for suggestions. Please submit a short description of your talk to IPv6-wg-chairs [at] ripe [dot] net. Merry christmas and hope to see you all in Dublin, On behalf of IPv6 Working Group Chairs, Marco Hogewoning
