I set this up during the Beta and it works reasonably well. Cloud Libraries behave just as Shared Libraries do in the App. I didn't see a restriction on the number of Cloud Libraries you can setup and they show up as available libraries in your Plex App. So I could see using the cloud server as a way to avoid eating up home server bandwidth if you do a lot of remote streaming. Particularly if your ISP has bandwidth caps. There might also be a performance benefit since cloud storage is faster than a lot of people's upstream connections to the internet.
