Hello There, I am also new here, but what you are asking for is called "Nested Shared" Check this out http://forum.bittorrent.com/topic/21334-nested-sharing/?hl=%2Bnested+%2Bshares#entry57158
@run4flat I have exactly the same problem, nested shares would solve a major obstacle I am facing right now with btsync (which I am loving!) If you ever come up with a work around please let us know
