Hmm I kinda recall a similar question some time ago ;)

Yes, yes and see below.

Along with that draft a good pointer to documents looking like:

Implementing AF-independent application by Jun-ichiro itojun Itoh:
http://www.kame.net/newsletter/19980604/ 
(Mentioned as AF-APP in the References section)

and:
Eva M. Castro's "Porting applications to IPv6":
http://jungla.dit.upm.es/~ecastro/IPv6-web/ipv6.html

Are good starting points. Maybe these can be merged into one document?
Especially Eva's seperate examples make things much clearer than
in the current draft.

Greets,
