I wasn't suggesting lower IPv4 efficiency as a solution to the IPv4
exhaust problem. I was stating the fact that if mobile operators want
their data services to look/feel/behave more like fixed ISP services
(DSL/cable/etc), then they will have to operate their networks
accordingly. I do agree that this creates a problem for mobile operators
who choose not to deploy IPv6. Since we're veering off the topic of this
thread, I'll leave it at that (I'm happy to continue the discussion
off-line if you'd like).
