I know of several significant implementers who would be willing to make
significant changes to their IPv6 stack, IFF it would have significant
improvements for IPv6.  Getting multi-homing into a scalable state would
be one example of a significant improvement.  Making mobility a 
first-order
property, rather than a "Mobile IP" add-on protocol, might be another 
one
(not sure).

Frankly, part of the implementers' willingness is caused by desire to 
see
their code get widely deployed operationally.  I've personally worked on
~4 different IPv6 implementations since 1995, and I don't see ANY way 
that
IPv6 will EVER be widely deployed given the current trajectory (i.e. 
there
is no significant win to migrating to IPv6 that is visible; IPv6 needs a
"killer feature", multi-homing or other routing improvements could be 
that,
the extant misleading claims of IPv4 address shortages is NOT such a 
feature).

As noted in a note earlier today, a significant change to IPv6 stacks
is one thing.  Throwing IPv6 out entirely is something entirely 
different;
I don't advocate the latter at all.
