Indeed. :)

Well, these arguments go for every device that is connected to a network 
that is ultimately connected to a network so large it is not within 
their control anymore, like the Internet, or other large WANs of the past.

The number of $ 0.5 million seems a lot to me, but I guess you have 
experience with that. I'm no corporate guy :). But still, do you think 
the argument still holds that developing for IPv6 now is cheaper than 
stacking hack on hack on hack for the next X years?

That smells of the often-seen lack of knowledge of manager types 
(Dilbert anyone?).
