Hi,

I do not think that a /64 per host is reasonable address usage.

To implement this, network admins need not only to add v6 subnets
to broadcast segments but also add pools of sizeable size, which does
create pressure in the /48.../64 range of the addresses they have
("one /48 per site").

Something like a /96 per host - so "limitless amounts of host would
fit into a single /64" would avoid that, and still fulfill the 
stated necessity of having many many many addresses per hosts.
