This is the business reality of the IPv4-scarce era.  Diluted IPv4 is
not new to many places and will become common in many more places.
Furthermore, it is a calculated business risk.  IPv4 services
will/have become the 2nd class (NAT444...)  services as IPv6 ascends
to first class status with e2e restored and more and more services
supporting IPv6 (World IPv6 day in a little over 2 week!...).

Don't get me wrong, IPv6 has a long way to go in terms of
availability, peering, and application support.  But make no mistake,
the tide is turning.  Rogers is doing what they have to do proactively
to stay ahead of the curve of complete exhaustion.

As for 6to4, the good folks at Rogers have found a way to make it work
for you ... with yet another NAT :)
