Good question. I would say yes but SCTP would permit one to treat them as
the same node yet different links (interfaces). But I think we need to
think hard about the question and all the matrix of answers.

Hmmmm... I am not sure we can assume this on the lower 64 bits...I need to
dream on that...Excellent question.
