Currently, a lot of people use Ubuntu One to sync their documents, pictures, .etc .etc between computers
This is a highly inefficient way of syncing files across computers, as it follows the path
Computer 1 -> (uploads changed file to Ubuntu One) -> (Notices changes and downloads) -> Computer 2
Unnecessary space, bandwidth, and other resources on Ubuntu One are wasted, and the process is slow and inefficient.
Instead, we should have a method to allow direct computer-to-computer sync through something similar to a p2p network. Sort of like Windows Live Mesh.
