File Sync
A simple unsecure way of syncing your files between your GNU/LINUX compliant OS's ;D
Warning
READ THIS: For the love of god, in current state don't use this with files that are of great security: ID card images(don't do it in general), banking records, those neat Lockheed Martin classified documents, or other files that may impose any kind of damage if exposed to the public
Idea
It just works
