You are probably correct here.  I did some digging into ical and get the
feeling that the ids are the same thing.

What I have done is to have a property called GOOGLE_UUID to keep track
of that item.  This way, if any other property gets added it probably
won't conflict and I can keep track of google stuff separately.

I am working on the logic to do that right now.  It is easier for me to
work in Python as I am not an elisp expert but I am going to have to
do *some* of this in elisp eventually.

I have had some confusion regarding repeated events.  Does this have
anything to do with what you saw?
