Is there something like FolderShare that I can run on my Windows and Ubuntu machines? I believe FolderShare had Mac and Linux clients before it was acquired by Microsoft but it seems to be gone now.
PS: I'm not interested in online backup services, just something that can keep specific folders synced between two or more computers without storing the file(s) in the server (P2P like).
Accessing the shared folders via an online interface (like what FolderShare used to do) is a plus.
Thanks in advance.
