I met Peter and Günther during the first half of 2011. Peter showed his
ideas and as I recall this part, the idea was to use a range of bits of
the IPv6 addresses to encode various policy settings.

W.r.t using IPv6 as a native transport Internet protocol for services,
it's at least the idea and aim with the concept, given IPv4 and
everything else is carried over the core encapsulated. 
See especially the box called "Legacy Protocols" in slide 4 of
http://wielandmedia.com/wp-content/uploads/2012/03/DT-0312-Clauberg-Transforming_Carrier_with_SDN.pdf  for their ambition in this regard.

AFAIK, there was then, and I cannot imagine it stopped, an extensive
engineering effort in DT on this from many angles, and I doubt it came
to a relatively large scale POC as it did, with too many design holes.

There are other issues to doing this, of course, which we were
discussing on IRC at length yesterday. :)

Best,
Martin
