How about simply making the IPv6 allocation minimum requirements mirror
those for IPv4?

From http://www.apnic.net/policy/add-manage-policy.html, an IPv4
allocation of a /21 is made if the LIR can justify a /23 now (section
9.3), and can demonstrate a plan to use a /22 in a year.
If we translate that into IPv6 equivalents, that would be "justify a /30
now, and demonstrate a plan to use a /31 in a year to get a /32" - which
is considerably more than the 200 (which is not even a /40) in the
existing IPv6 policy. Do we want to go here? 200 sounds a lot easier to
me! ;-)
You can mirror the concept without mirroring the details. For instance, you
could introduce a system that guarantees everyone as much space as they can
demonstrate they need. When an APNIC member demonstrates a need for x /48s
the would be allocated a block that meets those needs. This could be done
based on an HD-ratio measurement or some other 'fair scale'.
As APNIC use a sparse allocation model there would be a very good chance
that a future allocation would be contiguous with the first allocation.
