Rsync daemon setup
With a few tweaks it is possible to get RsyncOSX working with rsync daemon. Be aware of not utilizing ssh, transfer of data is not encrypted. This is might not a problem on a local network, but I would not advise it on a public network. Also be aware of snapshot is not possible with a rsync daemon setup.
Setting up a rsync daemon setup require a server side setup and some tweaks in RsyncOSX.
