I support the publication of this document.
While it was clearly an experiment and would have been suitable for publication as Experimental when it was first written, I agree with Jari that as time has moved on, thi should be published as Informational to describe the experiment that has been completed with lessons learned.

I have a minor question about translating unmapped IPv6 addresses.  In section 3.6:

   [...] the inverse
   mapping for unmapped addresses is defined in this document.  In the
   current prototype, a pseudo IPv4 address is generated.

I can't find the the description of the inverse mapping or how the prototype generates the IPv4 address.  Nit: I assume the generated IPv4 address is a real IPv4 address, so "pseudo IPv4 address" isn't quite accurate.

In Appendix B:

   Note that the non-IVI IPv6 addresses are mapped to,
   which is defined in this document (the first two sections are the
   IPv4 prefix of /16 of the IVI translator interface and the last two
   sections are the autonomous system number 4538).

I don't see any other occurrences of "" in the document, so I'm not sure what the text is referring to.  I also can't find the definition of the translation (for clarity, I would call this a "translation" because the IPv6 address is "unmappable"), which I'm guessing is referred to in the parenthetical text.

  The Gen-ART Review by Elwyn Davies on 4 January 2010 provided many
  suggestions for greater clarity and many other editorial improvements.
  Please conside these suggestions.
