Let's say you are sharing pictures with your friends and you want them to access those pictures even when your computer is offline. That would mean that those pictures need to be stored on a server from where they can be served. So, we can rule out your computer.

How do you propose that we store the data in this case? I can only think of storing it on some server in an encrypted form. Your thoughts?

Depending on the intended distribution, I might use DVDs or printouts or other kind of physical media like that. But, for some uses that won't do, so then you would encrypt them and store them on a server.
