Bill:

Interesting analogy, but it misses the larger point.  The larger point is 
that the ongoing effort to squeeze more mileage out of IPv4 will soon [1] 
outweigh the mileage we (collectively) get out of it.  IMHO, that effort 
is better invested in preparing for and deplying IPv6.  Things like 
LSN/CGN are stop-gaps that result in performance problems for people 
behind them, and aren't terribly useful for people who need to run inbound 
services.  Shaking down entities (to the extent that they can be shaken 
down) that have chunks of IPv4 they're not currently using doesn't change 
the end-game for IPv4.

I'm not saying that there aren't challenges to deploying IPv6.  There are. 
Like many of the people on this list, I run a network, and I'm familiar 
with many of those challenges.  If a network makes a conscious decision 
*not* to deploy IPv6, that is certainly their choice, and they will have 
to live with the consequences and will have to justify that decision to 
their customers.
