I just finished home lab setup with Apache + Centos + WebDAV
On 1 machine
that is connected to 2 other glusterfs peers working in replication mode.
It felt good when everything worked as expected. and I can connect via WinSCP, and it recognizes passwords for users created by Bcrypt which I reckon uses Blowfish and over HTTPS which makes it very secure.
umm.. its lame abit that each folder/share you will need to define in it apache webdav.conf, but if you want to implement something manually that is the price you pay.
Other than that it is all good, you can create personal shares like HR , and other Public ones. And replication does occur by the underlying glusterfs.
