according to the presos at ARIN this week... it's pretty simple to get
your for-real addresses. one would suggest a solid numbering plan, and
understanding of what technology you may need to employ for your
deployment are good to have in hand, though not required for initial
assignment.

Do you need 6rd because of standards/equipment failures in your chosen
deployment? Do you have other technology driven requirements?
Hopefully in your testing with the fun HE tunnels you've found out
what is possible and NOT possible in your build, yes?

of course, no one should deploy production services on tunneled
transport... well, free-tunnels :), and with the expectation that
renumbering will be required at some point in time.

that probably depends a LOT on what sort of ISP these are, and what
their deployment today looks like (for v4 services). For instance, are
they a:
  o hosting company (seems like fairly simple 'drop a v6 addr on your
gear, slap one toward the customer-ip, done!)
  o transit/business ISP (put ipv6 on your devices, offer prefixes to
your customers, done!)
  o consumer ISP (cable/dsl/ftth/etc - see deployment situations for issues)

For the consumer-isp folks... that's where 6rd seems to be necessary
(depending upon their deployment scenario today, of course, it's not
at all a forgone conclusion that 6rd is required in all of these
deployments)

So, in short, it depends a lot on what things the ISP is required to
do... prescribing an answer doesn't seem helpful :( (or so far the
'/32 for isps' answer hasn't been helpful)
