Here are couple of scenarios:
-------------
Friend: Hey buddy, do you have 'Scent of a Women' with you?
Me: Not sure but let me check it right away
I opened Plex app on my iPhone but damn the app is not able to connect to my media server bcoz maybe my machine is shut down, I can only see the synced content and not my entire library.
Me: Sorry bro.. I can only tell you once I get home.
-------------
Friends: Let's do a movie night out at your home
Me: Sure, what movie would you like to watch?
Friends: Well.. what movies do you have?
Me: Let me show you right away..
Arrgh.. server down not able to access my catalog
Me: Sorry guys.. let's head home and we'll decide it there only
-------------
Now wouldn't it be cool if there is a way to access my entire library even if the media server is down? It could be by making the whole library catalog metadata sync to a cloud server or maybe some other smart way of handling this scenario.
The idea is to be able to see your whole library content anytime. If the server is down, you can still browse through your library but will not able to play any media.
