Just to clarify, Mezzmo server always streams content from from itself - no matter the location or type of that content (file-based, URL-based, channel/plugin-based). There is one exception - network media that has been added into your Mezzmo library via the Network Media pane is presented to your devices & web browsers using its original URL/location (if the URL does not require transcoding for your device or web browser).
