The issues which are the subject of this paper cover an extremely broad field. In themselves the components of the topic could be the theme, in considerably greater detail, of a two day seminar._x000D_
Indeed a full course in an academic year would probably not do justice to the topic. I have therefore experienced considerable difficulty in condensing such a broad subject range down to a 30 minutes address and in doing so have tried to, hopefully, provide a little bit of everything for the wide range of professional interests and different levels of commercial, professional and legal expertise represented at this conference. Perhaps my address could best be described as a "bird's eye" view rather than a "worm's eye" view of the subject.
