I'll post a small guide for newbies that want to set up SF sync using WinSSHD as the file server.
If this is available somewhere else please tell me to save me the work.
Sources I'll be using/referencing to are listed below, so it should already be enough for most people, but I'll make this easier in a few days when I am sure no one has posted this already somewhere else:
http://www.bitvise.com/winsshd-for-sftp
http://www.superflexible.com/partial.htm
Later I'll add:
http://www.superflexible.com/mangling.htm
http://www.superflexible.com/restore.htm
I won't be covering certificates at all, although it could be useful. But I don't feel like the right person to explain other users about this kind of feature
I'll probably finish this in 2-3 days
