The interesting thing is that people don't spend cycles thinking about
any of the NAT-induced glitches which cause end users to lose sessions;
some of these will apply to NPTv6 of course. I wonder if it's possible
to quantify this (rough % of sessions lost by NAPT44 glitches, and
how many of these would *not* occur with NPTv6)?
