Makes sense.

Richard, you said that the consensus was for a /64:

A /64 seems small -- recall that the IETF draft on IPv6 allocations (not
currently adopted as ARIN policy) says:

"-Home network subscribers, connecting through on-demand or
  always-on connections should received (sic) a /48.
- Small and large enterprises should received (sic) a /48...

- Networks with a clearly expressed disinterest in subnetting
  should received a /64.
- Mobile networks, such as vehicles, cellular phones should
  received a static /64 prefix to allow the connection of multiple
  devices and, depending on the architecture, a /128 for a
  MobileIP care-of address [MobIPv6].
- Subscribers with a single dial-up node preferring a transient
  address should received a /128.

Note that there seems to be little benefit in not giving a /48 if future
growth is anticipated..."

So RIPE NCC felt that a /64 was more than adequate?
