A large aspect of our business is running data centers.  Typically
we drop off a 100Mbps FE, or 1000Mbps GE link to a customer who
plugs in a number of layer 2 switches and installs many servers.

As far as I can tell the best thing to do with these customers is
assign a /64.  A shorter prefix would be a waste, as they own no
layer 3 gear, so they would have no way to break it into separate
lans anyway.  I suspect anyone who runs data centers will generally
be assigning /64's in the data centers to customers.
