Ad-hoc presentations If the previous presentation was missed, or had
to be reviewed by new employees after the initial presentation, this
method of delivery allows for content on demand at the pace of the
user. However, this is a one-on-one media stream from the media server
to the user, and is not a multicast presentation. If dozens of users activate
this type of presentation at the same time, then the network would
experience a sizable jump in utilization without notice.
