Open source alternative to Dropbox?
I am looking for an application that works in both linux and freebsd (windows would be a plus) that keeps a file tree in sync in the background like Dropbox does. I can no longer use Dropbox because it does not support FreeBSD (you might see a forum thread saying otherwise, but its fix is out of date). The application does not have to sync to a separate web server, I can host from my house, but it would be nice. A system tray icon to check on state would also be nice, but not required. The platforms that I really need are kubuntu 9.10 and FreeBSD 8.0.
The simplest thing I could think of would be a script that had git update a repository with all my docs in it every minute or so, would this work?
