I can only answer one of those many questions: Hot linking You can easily intecept the connection-creation at serverside to do some hot-linking prevention. For example: you create customizes URL for your VOD files, which contain an encrypted timestamp (to ensure a limited lifetime of the link). And when flashplyer tries to connect to red5 server with such customized URL, your red5 serverextension would decrypt and validate that timestamp and only connect, if that was successful.
