That would be great :)

Probably you have - and I do not disagree with you. Nevertheless, from a
recent event at a the local film studio and discussion with experts in the
area, I have the impression that in movie industry business reality both is
an issue - that is, setting up the chain between the hundreds or thousands
of people in video / movie production, and being able to pass properties
along the way. Do we have people on this list who are in video / movie
production and could comment on that?
