PlexNMTHelper is a Java program that enables remote control of your Networked Media Tank (200 series or newer) as though it were a true Plex client.
It can be used with Plex Mobile (iOS, Android, Window Phone 8, or Window 8) and Plex/Web.
It discovers the Plex Server on your network and announces itself as a Plex client. This allows you to fling media to your Networked Media Tank and control playback.
