Why a single /64? You certainly won't be only getting just a /32, and
I'm sure you've got way less than 4 billion customers. A /60 would have
been a conservative option if you wanted to dip your toe in the water,
yet still would allowing people to use subnets in their home if they
wanted to perform some of their own experiments - your trial
participants are more likely to have a few routers in their home that
they may want to use to experiment with IPv6 and IPv6 routing.
