That is my experience, too. When I was in IT, my response was to block
IPv6 at the firewall (until I learned my firewall was incapable of
examining IPv6 packets and therefore allowed ALL IPv6; I wasn’t allowed to
change firewalls so I used a router ACL to block it while I reviewed our
IPv6 security policy and looked for another job). When I was at an ISP, we
could route IPv6 to the customer, but until they enabled it, no traffic
would follow.

I think you’re talking about business education, not technical IPv6
education, right?
I recently posted my suggested technical reading list:

But I think you’re asking for a business education series that goes:
1. Enterprise business consideration of IPv6
   a. It’s already on your network. All computers, tablets and phones have
at least Link Local, and some set up tunnels. Plus, if your employees have
dual-stack at home but single—stack VPN, you may not like your split
   b. Lower latency.
   c. Using IPv6 in interesting ways, like Segment Routing, Terastream bit
masking, IPv6 address as process ID.
   d. IPv4 runout doesn’t matter much to most enterprises. They only need
a couple of addresses for new branch offices. Those enterprises who have
their own IPv4 address block (from RIR, not ISP/LIR) should consider how
much they could sell it for. At $15/address, a /16 approaches US$1
million, which is real money to most CTOs.

2. Enterprise IPv6 implementation guidance
  a. https://tools.ietf.org/html/rfc7381  “Enterprise IPv6 Deployment
  b. Cost to Renumber and Sell IPv4

I’ll see if I can write up #1 into a single paper or blog post in the next
few days. Anything else I should add?
