I have not solved using BT Sync directly as I think BTSync also needs to be running on the server side (per 12345lamacun). What I have done is to use another sync program (SynKit; Mac) that will sync my local drive with the network automatically and daily. Then BTSync handles the immediate synchronization across all of the "local" drives. If I need to be sure that a file is synced immediately I have SynKit do a manual update and the BT is automatic. Maybe not the best system, but that is what I came up with. Would be happy to hear other possibilities.
