I'm using btsync (1.0.134) on 3 linux machines (32 and 64 bit Ubuntu and 32 bit Debian wheezy) and am experiencing sync issues with long file names. In order to provide enough security to store my data on untrusted hosts, I use encfs (https://en.wikipedia.org/wiki/EncFS) to encrypt my files. Unfortunately, encfs creates very long file names, for example /home/ifoo/.encrypted/Documents/0ZmxrOATx4YgPC5jBr4gRkKU/-VljqWC1rAVUjB9GnB,iaBRY/3NeHN3GTSu5BSe9k9kKE1,T-/hYMaULYtXDVXkWcjRU1Y954D/x,u0qWitYS9Xl1E-mjxjzKMpi,XdoikblNSE0kJVDMKEkDvShNXVvgWmJTBUl6IzSzq1JmAPbBmcHc6Tx39Ao9dYvaatj890Q-HFooH,u,aE-wX-
