I would support Paul's proposed changes below, and the resulting draft.
I wouldn't, at this time. We need to see where the RAM/RRG discussions
lead. If they lead to a clear need for registered globally unique
identifiers in IPv6 address format, something like this might be right
(unless we also need a cryptographic property).
I have a strong feeling there is no consensus forming...

these are my comments on the following I-D:
Title : Centrally Assigned Unique Local IPv6 Unicast Addresses
Author(s) : R. Hinden, B. Haberman
Filename : draft-ietf-ipv6-ula-central-02.txt
Pages : 11
Date : 2007-6-18
<http://www.ietf.org/internet-drafts/draft-ietf-ipv6-ula-central-02.txt>
first, in 3.1, this table:
| 7 bits |1| 40 bits | 16 bits | 64 bits |
+--------+-+------------+-----------+----------------------------+
| Prefix |L| Global ID | Subnet ID | Interface ID |
+--------+-+------------+-----------+----------------------------+
should be replaced with this one:
| 7 bits |1| 8 bits | 16 bits | 16 bits | 80 bits |
+--------+-+----------+---------+---------+----------+
| Prefix |L| Reserved | RIR Num | LIR Num | User Num |
+--------+-+----------+---------+---------+----------+
where "Prefix" and "L" are defined as shown in central-02, and the other
fields are defined as follows:
Reserved Set to 0 by all implementors of this
specification,
but may be set to nonzero by implementors of
a later
specification.
RIR Num Identifiers assigned by IANA for each /16 as
allocated to an Regional Internet Address
Registry
(RIR). For direct allocations by IANA, the
value
of zero (0x0000) is reserved.
LIR Num Identifiers assigned by RIR for each /32 as
allocated to a Local Internet Address
Registry (LIR).
For direct allocations by an RIR, the value
of zero
(0x0000) is reserved.
User Num Identifier assigned by an end user or network
operator who implements this specification.
second, delete all of section 3.2 including subsections 3.2.1, 3.2.2,
3.2.3.
third, replace section 7.0 with the following:
---
7.0 IANA Considerations
IANA is hereby instructed to reserve address block FC::/7 for private
unique addresses, and to allocate /32 blocks to Regional Internet
Address Registries (RIRs) who request same after adopting policies
consistent with this specification. Allocation shall be similar in
all ways to normal IANA address allocation to RIRs, including but not
limited to IN-ADDR.ARPA delegations and WHOIS records.
