  If it's a unique ***LOCAL*** address, then why is it a problem if
multiple places on the planet use it???  Doesn't sound very "local" to
me.

  Probably the easiest conversion for most people would be to do what
was done with TV sets...

* When analogue UHF stations first came out, you could get a "translator
  box" that had a tuner which translated UHF channels to channel 3 or 4
  on your old VHF-only TV set

* When non-encrypted analogue midband channels came out on cable TV, you
  could get a "translator box" that mapped cable midband channels to UHF

* When ATSC (digital) broadcast TV came out, you could get a "translator
  box" that converted ATSC signals to NTSC, and fed them to your old
  non-digital TV set.

  Too bad that NAT-PT has been deprecated.  It could've been the
transition answer.

  Don't get me wrong.  I agree that eventually we'll have to transition
to IPV6.  I held off going 64-bit on Gentoo, until I got a machine with
more than 3 gigs of RAM.  Similarly, one of these days, I'll eventually
do an IPV6 install.  What I did not appreciate was the day when the
"ipv6" USE flag was added as a default.  I found out about it when
Firefox started taking a minute or so to find sites, i.e. timing out on
the IPV6 lookup before failing over to IPV4.  Since that day, I start my
USE flags with "-*" in /etc/make.conf to avoid similar surprises.
