As an aside, I've been using Sparkleshare (built on GIT and SSH) lately. It's pretty good, and sucks up less battery on my MBP than the Dropbox client (maybe because it's not watching every file in the system!) And not only is it open source, but you can see a log of all the git commands and fix things manually if necessary.

My only lament is that it doesn't work that well over the intermittent connections. It'd be neat to have something robust like mosh (https://mosh.mit.edu) for file sync.

There is also unison; it is not automatic (custom inotify script is required to mimic Dropbox, and it will force manual intervention upon conflicts) nor stores history, but handles large blobs, many clients and crappy connections quite well.
