When you can plug your computer in, and automatically (with no
clicking) get an IPv6 address,

Router Advertisements let you automatically configure as many IPv6 addresses as you feel like.

> have something tell you where your DNS assist servers,

Microsoft had an old expired draft with some default anycast IPv6 nameserver addresses:

   fec0:0:0:ffff::1
   fec0:0:0:ffff::2
   fec0:0:0:ffff::3

-- http://tools.ietf.org/id/draft-ietf-ipv6-dns-discovery-04.txt

While this was never accepted by the IETF, I believe windows machines still use these by default if they have no other name servers but do have IPv6 connectivity.

This could be a fairly simple defacto standard if network operators start using it. This is an obvious weak link in the chain at this point tho.

once you have DNS you can use the WPAD proxy auto discovery thingamabob.

and solve your dynamic dns problems (as IPv4 set top boxes do today),

Updating your forward/reverse dns via DNS Update messages isn't that uncommon today.

See:
http://www.caida.org/publications/presentations/ietf0112/dns.damage.html

where hosts are trying to update the root zone with their new names.

So you can get from A to D without requiring DHCPv6.
