>2.  Has anyone ever observed a cluster move sideways during the winter?

I think Tibor Szabo illustrated this happening in hives fitted with thermocouples back in the seventies.  The movement over time is illustrated in his paper which, I cannot locate right now.  His site is http://honeybees.ca/research.html

>3.  Has anyone noted the definition of CCD being changed by anyone in response to the Harvard study?

That would be changing history.
