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.
