I'd say it's going to be quite common that there are multiple customers in 
a single /64.

There really should be some kind of mechanism so the ISP can indicate 
entity/subnet relationship, for instance if a /48 belongs to a single 
entity, or if multiple entities can reside within the same /64, and if 
these entities will have just a single IP per machine (strict DHCPv6 and 
no SLAAC), or if SLAAC is in effect and a box can have any IP.
