In IPv6, the current policy is that you have to either qualify for an IPv4 
assignment (~1000 hosts multihomed, or ~4000 singly-homed), or already 
have an efficiently used direct IPv4 assignment under RSA.  For smaller 
networks, current policy encourages them to get an assignment from one of 
their upstreams.

There have been proposals to make v6 assignment criteria independent of 
the v4 criteria, and I suspect at some point we'll pass something along 
those lines.

That's still correct.  ISP (LIR) assignments are /32 or larger, and 
end-user are /48 or larger.  The main justification for the LIR /32 
minimum is to make sure that they never have to come back for space, even 
when using a hierarchical assignment model on byte boundaries (i.e. a /40 
per region, and /48 per customer).  It's also somewhat helpful to have the 
same size on most allocations, for ease of filtering.
