I agree that you can limit the speed. However, I can run faster speed. But if you download a large volume traffic, there will be questions from the administrator. In principle, it does not matter, but for someone can be there would be convenient. I'm more interested in the issue of synchronization when the computer is turned off. In the next branch is also seen suggestions for using Dropbox to sync. I made a sketch of the first post on the basis of the work of this synchronization. I think that build dropbox in SyncApp not need (especially since it will be a violation of copyright), as can simultaneously run the application from the dropbox.
