I would say in your case that it IS a nightmare.  It's a financial
nightmare.

Did the CGN box you put in save you money?  It seems to me that it
did not.  It seems to me you spend a lot of money 3 years ago to do
this and that expense did nothing to get you more revenue.  It seems
to me that if you HADN'T spent the money on the CGN box that you
would still have those same 100 customers today, you would have the
last 3 years * 100 in revenue from them - you just wouldn't have the
loss of money you spent on the CGN box.

Without a financial analysis to go along with your statement, you
really aren't seeing the entire picture.

With IPv6 we can do the shift from IPv4 to IPv6 by simply LEAVING ALONE
all existing IPv4 customers and doing the work of shifting to IPv6
with the NEW customers.  Then the revenue from the existing customers
pays for the labor to add customers.  Since after all you already have 
to to the work of adding the NEW customers to your network because you 
have to add network to your network, your spending money.  That is 
Business 101.

With the CGN way you have to go back to your revenue producers - your
existing 100 customers - and do the work to shift them over even if
all your doing is reworking your existing network.  While you are doing
that your incurring labor costs that have to be paid, and your going
to pay them with revenue from the existing 100 and you won't be able
to pay to add new customers.

I know of no business that makes money by continually spending money
on it's infrastructure and getting nothing back.  All profitable 
businesses I've ever seen expect that for every dollar they spend
they get 2 customer dollars back.  They also expect to use the
infrastructure for many years.  They can do that with IPv6 by leaving
IPv4 alone and just adding new customers with IPv6.

Incorrect.  I was around back then and the goal WAS end-to-end
reachability.  The difference was that hosts then had lots of
users connected to them with RS232 terminals.

Wrong because most people back then dialed in with a modem using
a terminal emulator program.  The first connectivity was e-mail
gateways between the Internet and BBS networks like FidoNet.
The WWW came about later and it still wasn't that interesting until
pretty late in the 90's, around 96-97.  And NAT came about when
most home users were still using dialup to connect to the Internet.

logmein is not free for business use so your probably violating TOS.
And if you paid for it why should everyone else in the world pay
that company?  Remote Desktop is free for business and personal use
and does not require some wacky active x control or java applet to
run in a browser.  So is VNC.  both of these are also faster.

They OFFER CGN on their big iron they don't "enable" it, the admin
has to configure it for it to be enabled.  And naturally they don't mind
if an admin does because they get to sell them more hardware that way.
