Best way to sync two computers?
I would like to be able to sync files across my computers (Ubuntu, Windows XP and Windows 7). Ideally, it would be easy enough for my family to use. Real syncing (not just a shared folder), is important so that my brother can access files on his laptop wherever he goes.
Unfortunately, I have quite a limited Internet Download/Upload limit and so I don't want to chew up my usage with synching. Is their anyway to only sync over a LAN?
