Well here in Australia I would be calling the ACCC is a ISP tried
to charge extra for a address that is not behind a LSN.  As for in
time it should be in place before they turn on LSN.  If you can
adjust port 25 filters whenever a customer gets a new address you
can also ensure that they get address from the correct pool when
they connect to the network.  This really isn't rocket science.
It's updating the provisioning database from a web form and generating
new configs based on that database.  Yes there is some work required
to ensure that this gets done properly and there needs to be checks
that address pools are appropriately sized.

If I were doing it I would also have checkboxes for some of the
more common reasons and include IPv6 connectivity as one then have
a 6 month grace period once the ISP offers IPv6 connectivity before
removing that as a valid reason for needing a address that is not
behind the LSN.
