Hi Brian,

I hate to be a pest, but does this mean you favor eliminating strategy
B from consideration? Or oppose?

I respect that your views on the subject are complex and that you
would choose to ask and answer a more subtle question. But I didn't
ask a subtle question.

There are also forms of strategy A that can evolve into strategy B
over the long term. Architect your ITR so that the pushed data load
doesn't render it unreasonable to place the ITR on the end-user's PC
and then build the ETR dumb. With the session knowledge not available
to the network ITR, the host ITR can make a better decision. Over time
it becomes a standard part of the stack.

Name three such applications. No points for layer-7 multihoming or
applications which are obscure even within the IPv6 community.

I'm not the IPv6 expert that you are Brian, but your statement does
not reflect operations-level reality.

Bill Herrin
