Have you spoken with OS distributors in order to have this change
included in their patch management system? That will make the
transition a little bit better.

Also, do you have plans to capture traffic on a regular basis to keep
track of the transition process? More than a few researchers lurking
on this list will be very interested on that data :)

I'll pass your notification to the New Zealand Community.
