That more or less sums it up, thank you. :)

My desire to get further arguments, is that due to my agreement to the 
ideology, they wanted second opinions from someone else hence the question 
to the mailing list. So basically there are only two options, as far as I 
see it:

1) Do CGN/MAP/lw4o6 and degrade the service somewhat, for 75% of the 
customer base it does not matter but there are still 25% of the customers 
who cares. Find incentives to persuade existing customers to let go of 
their native IPv4 address.
2) Buy more addresses for now, and do not degrade the service.

Anyways, thank you all for your opinions.
