Hi, I'm doing something similar, but instead of BTsync, I use ssh & unison/rsync. The remote pi calls back the main pi by ssh. The main pi uses this connection to sync files. So the remote pi can be behind a firewall and no issue. Im interesting in sharing the setup - and improving it, if anyone interested let me know. Im at padrone.nl
