Hi Pekka,

Do you think that this document is ready for WG last call for
informational, then?

I've been wondering about the same too, due to lack of feedback since the
last revision from the WG.  I must assume it's perfect ;-)

True enough, they should make it easier to implement 6to4 properly.  This
is also possibly something that could form a basis on what to ask from the
security side if we progress 6to4 to Draft Standard one day.

Pretty much agree, informational seems to be the best way here.

If we need to fork off separate efforts to modify 6to4 spec or augment
that, it should be in separate, short documents referencing this.

In short, it seems to me that we can't find a proper solution that would
satisfy everyone at the moment (and we may not even need one really
badly), so it might make more sense to just push the documentation of the
issues out and leave specific solutions for later.

Easier to get consensus on this than a specific solution, I think.
