Please rememeber, that I also suggested a technical solution: calculate the
IPv6 addresses (subnet) from the previously allocated IPv4 address of the
DSL user!

That means: if we are able to allocate IPv4 addresses in "pseudo dynamic"
way (wich is rather static), then we will be able to allocate IPv6 networks
roughly at the same way.

No. I try to draw a line between "light" service and "serious" one (Or:
between "dummies" and "experts".)

It won't help, unfortunately. How many people live in Holland? How many SIM
card (mobile phone contract) exist? Much more, than people...

Different allocation criteria also mean: sparser usage at the beginning. If
we allocate an IPv6 subnet to each and every DSL costumer, very few of them
will realy use it at the beginning. However, fast IPv6 transition is not
possible without this "generosity".
The suggested size of the "anonym" pool is depend on the number of
costumers: a /36 for very larg ISPs (more than 15 million costumers), a /40
for medium ISPs, a /44 for smaller ISP-s (less than 1 million costumers)
Yes, there are ISP-s serving more than 15-16 millions costumers! This is one
of the reasons why I suggested the creation of a new type of reusable
addresses, the AS-local IPv4 address pool!
