Personally, I think /64 works just fine.
I continue to believe that the "allocate the /64, configure the /127 as a workaround for the router vendors' unevolved designs" approach, which Igor and I discovered we were in violent agreement on when on a panel a few NANOGs ago, is the right one. With only between 2^34 and 2^35 neocortical neurons in the average human brain (*), perhaps we ought to be engineering for conserving human brain cells rather than IPv6 addresses. That means encoding metadata in the IPv6 address in an easily visible fashion (such as pop aggregation on nybble boundaries) and having a scheme where all subnets are the same size (and just happen to hold an arbitrary number of hosts). -r (*) a figure that is as irrelevant to the current conversation as Roland's grandstanding about rejecting arguments about the vastness of the IPv6 space out of hand).
