Which is what DHCP(v6) is good at, and it may not be overkill if you also 
want to run a v6 only network and also use DHCPv6 as your DSTM server, for
example.

I think in many situations you'd expect a static prefix, but there may
also be situations where any prefix is OK and so a static dhcpv6 mapping is
not necessary.  This might be useful in the MONET area to get a temporay
prefix for a mobile network, so we shouldn't perhaps constrain thinking to
fixed CPE?
