BitTorrent launched a new tool which is being a success to sync files between devices, in a encrypted and simple way. It's called BitTorrent sync.
You can get the package for arm devices (and others), here:
http://labs.bittorrent.com/experiments/sync.html
Don't know if it helps, but there is a package for the Synology NAS here:
http://www.synocommunity.com/packages
It has a simple web interface and would be a great addition to Alt-F.
This is a closed source/proprietary program.
Try following their instructions under Alt-F for the distributed ARM binary and report back if it worked.
It seems that I have already done it, and seems that it can't be used with Alt-F:
