Sweet. I'm a Plex Pass member, so I'll check it out. I wonder if this also explains why Plex Pass subscription rates went up for all new subscribers. I just jumped on the $75 lifetime subscription before the price change, which also gets you free Android and Roku versions. Albeit, I don't actually use either of those devices.
You don't use PLEX simply for streaming. You should more or less think of it as a simplified whole-home version of XBMC. For example, I can start up a movie on my phone, stop it, pick it up in the living room, stop it, pick it up in the bedroom, stop it, and pick it up on the phone again. Note that there's no difficulty in any of this apart from selecting to resume when I hit play. Also, PLEX handles the re-encoding based upon device profiles.
