I agree. Although I believe some ISPs will put multiple customers in a 
single /64, this is mostly going to be dynamic customers anyway (multiple 
laptops on a wifi for instance), and those I would imagine are treated 
with the same policy so it doesn't really matter. Per /64 handling is a 
reasonable tradeoff between granularity and practicality in my mind.
