"Leasing" of space via non-connectivity providers

I was having fun discussing with my wife how ARIN stuff ended up on 
NANOG, NANOG stuff ended up on PPML, and I've been listening and 
participating in debates concerning IPv6 and CGN (apparently BEHAVE WG 
adopted CGN over LSN) on 4 different mailing lists.

To be honest, though. I'm pro-IPv6, but I'm not happy. Anyone who is 
happy doesn't care about those innocent people who are ignorant of what 
is going on and why.

Doing this on some of the consumer networks will likely not be "that much" pain.  Obviously the pain will vary per subscriber/home.

Service requirements in cellular networks are considerably different 
than wireline. Apparently, most cell customers don't hook a CPE router 
into their cell network and play their game consoles over it, along with 
many other situations. This actually means that most often, they are 
running a single stage NAT44 LSN (which still breaks stuff, but most of 
the things it would break aren't normally transiting the cellular networks).

<snip more good stuff I agree with>

I agree. However, because the largest networks and corporations decided 
(and some still do) to wait until the last moment to deal with IPv6, we 
will have to deal with IPv4 in much worse conditions. I know that there 
are large cellular networks which use DoD bogons behind huge LSN 
implementations. I know that some networks apparently aren't happy with 
using DoD bogons and would like to waste even more space. The best 
solution for such a case (and to solve all arguments on the matter) is 
to secure assurances on the bogons so that they can be safely used.
