Installation guide

For example, an application with dierent membership levels could use the Authorization
plug-in to deliver a high-denition stream to a paid member, and a standard denition stream to
a guest. You would intercept the client before they connect, determine their membership level,
then lter the connection to point to the correct stream le. is plug-in could also be used for
access monitoring, logging, or implementing other custom rights management schemes. Since
these Authorization plug-ins can be chained, you can implement a sequence of actions to create a
sophisticated access lter for your content.
