The comment I had on the mike during behave session 2:

This kind of work is very valuable, it is worth not only for CGN but
also for Port Ranges solutions and for all IPv4 shortage solutions. 
As we presented it in the shara BoF all solutions basically:
1) Put a dedicated function in an ISP Box (CGN, PRR, whatever)
2) Use some sort of transport mechanism (tunneling, layer 2, whatever)
between customers and ISPBox, 
3) Are confronted with the same issues: how to force a route from
customers to ISPBox, how to route back from ISPBox to relevant customer,
how to identify the customer. 

This would advocate for seeing all work related to IPv4 shared addresses
host in the same place, under the same ombrella.
 

Regards
