I would strongly suggest that customer is not allowed to source packets 
outside if his/her assigned IP space. So if link-local can be used for all 
packets (when customer has a router), we get a very nice demarcation and 
can do filtering where we know that our infrastructure is in a certain 
IPv6 range and customers are in another, and we know none of our equipment 
is in customer space and vice versa.
So if possible, assign and route the /56 or /48 to the customer router and 
this router then needs to make sure it uses its internal IP to source 
packets destined for global Internet.
