Hi, Tom:

1)    Your caution advice to Karim is professional. With a lot of 
convoluted topics behind it, however, the net result is basically 
discouraging the listener from investigating the possibilities. Since 
this is rather philosophical, it can distract us from the essence unless 
we carry on a lengthy debate. Instead, I would like to address below 
only one aspect that you brought up.

2)    "... an operator clearly looking to acquire *publicly routable* 
space without being clear that this suggestion wouldn't meet their 
needs.  ":

     Since 240/4 has 256M addresses while 100.64/10 has only 4M, a 
current CG-NAT cluster can be expanded 64 fold once the 240/4 is used. 
Looking from another angle, an IAP will then be able to expand the 
subscriber set 64 fold with still the original one publicly routable 
IPv4 address.

3)    This 64 fold scaling factor is critical because it allows one 
CG-NAT cluster to serve a geographical area that becomes sufficient to 
cover a significant political territory. For example, if we assign two 
240/4 addresses to each subscriber, one for stationary applications, one 
for mobile devices. And, each 240/4 address can be expanded by RFC1918 
netblocks (total about 17.6M each). Each CG-NAT can now serve a country 
with population up to 128M. It turns out that population of over 90+ % 
of countries are fewer than this. So, each of them needs only one 
publicly routable IPv4 address. Then, the demand for IPv4 address is 
drastically reduced.

4)    In brief, the 240/4 is to substitute that of 100.64/10. So that 
the need for the publicly routable IPv4 addresses is significantly reduced.

Regards,
