You have Windows, MacOS, and Linux ... but no FreeBSD love? Would absolutely love you guys to death if you provided a binary for FreeBSD 8.3! And I say FreeBSD 8.3 specifically because that's what FreeNAS 8 is using. Running the binary from a startup script is just fine, and additional future features could include adapting for the FreeNAS plug-in system and allowing user/group permissions sync into various ZFS datasets. For example, say I have 5 users on the FreeNAS, each with their own dataset, it would be nice if btsync could keep the proper permissions for files transferred to each of those datasets (i.e., files into user1's dataset should chown to user1:user1). Right now I have a FreeNAS dataset mounted to a Linux VM, and btsync running on that Linux VM to a shared folder on the mountpoint. It works, but involves two systems and transferring all of the data twice (once to the Linux VM host, and then a second time to the FreeNAS mountpoint). btw, FreeNAS doesn't include the FreeBSD Linuxulator compatibility kernel module to directly load the Linux ELF binary. I also read elsewhere in the forums that folks were unsuccessful getting btsync to load on a full FreeBSD system due to lack of a specific call in the Linuxulator that btsync needs. Rumors are there's an alpha patch to FreeBSD 9 that enables that call. But again, FreeNAS's FreeBSD 8.3 doesn't include the Linuxulator kernel module, so no choice there but to have a FreeBSD-native binary available. Thanks guys! You rock!
