Why should I be required to leave my computer on 24/7 to share files with some friends?

[nitrogen]

Required? Perhaps not. But we "should" definitely have the option, and it should appear seamless on other devices with which we share files whether they're getting them from our own machines or from a private encrypted cloud cache.

You keep saying the word "should", but you're making a jump from what is (descriptive), to what ought to be (prescriptive).

This is the is-ought problem, or hume's guillotine.

Isn't that exactly what ownCloud is?
