Abstract
An internet presentation system includes an internet accessible server that permits specific types of access to a target presentation file by selected remote users. Only users having purchase access to the target presentation file may submit a purchase order for a copy of the presentation file. Each user is further restricted to the type of copy, video or data, of the presentation that the user can acquire. Users having purchase permission are further divided into owner status and buyer status. Users having owner status may grant or revoke the purchase permission of non-owner status users. At least one owner status user is additionally designated a super-owner, and can grant and revoke the owner status of other users. The super-owner user may relinquish its super-owner status to any other user.
