i'm thinking that the murmur could turn into a riot at RIR runout.  the
historical parallel is "prohibition", where laws against selling a certain
kind of commodity strengthened and amplified an existing black market.  i
recognize the imperfection of this comparison, since the scarcity was caused
in that case by the laws themselves, whereas the coming ipv4 shortage is of
natural causes.

that analogy fails since the first companies who go ipv6-only will all die of
starvation since "the internet" from their customers' point of view will be
mostly empty.  the first companies to go dual-stack are doing OK, we're getting
some small first-mover advantage by generating skills and tools, but there is
no first-mover revenue advantage in dual-stack.  the rational individual choice
for most companies has been some mixture of (wait-and-see and/or hoard).  to
the extent that there's revenue in dual-stack, it'll all be there waiting for
the stragglers.

michael, if my company was ipv6-only, then we wouldn't be having this
conversation.  i think onlookers know this and know that ipv6 won't help them
in the current fiscal year, but that dual-stack would cost them in the current
fiscal year.

the rational choice for many is: waiting until there are other ipv6 endpoints
to connect to before adopting dual-stack.  this isn't psychology, but rather
"just business" as randy bush sometimes says.

isc.org's network has been dual-stack for years.  what's bt.com's plan?
