To include: Most, but not all Plex features are available in today's beta. Some of the missing capabilities include Camera Upload and Offline Sync, though those will come in the future. Other features missing in Plex Cloud include DLNA support, Cloud Sync, Media Optimizer, and the newly launched Plex DVR. Note that Plex Cloud is not a copy of your local Plex server and Plex, as of today, doesn’t mention any type of media migration tool.
Wow! Sounds great!
