I don't think anyone, least of all the authors of 2007-08, thinks that 
it is a substitute for IPv6 deployment. Most people feel that this is 
the proper solution in an ideal world. However most of us feel that IPv6 
deployment to large consumer DSL networks is just not going to happen 
before IPv4 runs out and in that case some mechanism for recovery of 
unused space will be needed. Experiences with trying to get existing 
holders of unused space to hand it back without financial incentives 
(and regardless of what RIR policies say on the matter) make me 
pessimistic that altruism will save the day.
