Latest Sync Build: 1.1.70 in Sync General Discussion Posted May 18, 2013 · Edited May 18, 2013 by Lightning · Report reply In short: Yes.Syncronization is based on the torrent technology so the clients send chunks not files. If I remember correctly these chunks are 4MB so if your file is bigger than 4 MB and it doesn't transfers in a few seconds then other peers will help out.BTW supposedly Dropbox uses 4MB chunks too. What is it about this number?Edit: I just realized you're talking about multi-WAN. With one PC this is not possible until you can bind btsync to an IP or interface or somehow balance connections, but if you virtualize another one or if you have two PCs at home then I think so. Why haven't you tried it out?
