FYI. The intent is to discuss this on the IETF v6ops wg list 

But comments will be appreciated, regardless of the specific channel 
(whether on this list, off-list, etc.)

In the aforementioned document 
we have tried to do at least three things:

1) Look at what we have and try to discuss things from an architectural

2) Analyze the implications of #1 (whether operations, security,
    privacy, etc.)

3) Find missing gaps that currently prevent us from fully leveraging
    IPv6 addressing.

Part of what we've found as doing #3 above is that:

   * There are shortcomings associated with the current APIs that prevent
     better usage of IPv6 addresses

   * Multi-router/multi-prefix routing seems to be broken.
     RFC8028 would be a fundamental starting point in the right
     direction... but I believe there's more to do in this area.

In that light, we'd like to hear further comments on our document. And, 
in particular, we're interested to hear if :

   * there are any operational implications of IPv6 addressing that we
     have missed, or,

   * there's anything related to IPv6 addressing that you consider to
     be currently broken or problematic, that is missing in our I-D.

Thoughts on the current contents of the I-D are, of course, also very
