Volume 1 of this study describes and costs two possible satellite networks which could be used in education in Canada. In order to determine whether these networks were plausible or useful, a letter and a description of the two hypothetical networks (Volume 2) were sent, before the cost study was completed, to all Canadian universities and provincial Departments of Education, as well as to other bodies likely to be interested. This report contains a second letter, an expanded description of the two hypothetical networks, and the costing information, not available at the time of the first letter, all of which were sent to the same audience as the first letter. All of the replies to this second letter are provided and they are compared with the replies from the first inquiry. (DAG)
