This article first defines the scope of enquiry, then surveys some of the existing literature, and finally, presents the results of my preliminary survey interviews and questionnaire. It is my hope that it will serve as a basis form discussion leading to better definition of the problems for research in this area, and will suggest ways to proceed to gather the information necessary for more sophisticated exposition and commentary.
