[Top-secret, burn before reading!] It can.
And on my early experiments, when the /64 was the only block I had, that was really great.

No. The /64 is the default subnet size, and people normally SHOULD NOT (as in FTA-1006) split these blocks further, but that IS possible and NOT prohibited.

IPv6 is not that strict as, for example, IPX was.

Here in Russia the de-facto standard is one MAC-based IPv6 address for the outer-side link and /64 subnet routed via that address to the customer's LAN. Additional subnets may be requested as well, but ISP admins say most people don't request them.
