Damn that looks sweet! I didn't even know about it! CentOS 3-based. I'm sure they haven't addressed failover and many other concerns, and it's not an "all-in-one" like old SME Server (fka E-Smith), but it's definitely a nice, entry-level "Filer".
I think there is new life in the e-smith project. We are running A test on the latest here and seems to work quite well for A small office setup. Also joined their list, and updates/fixes Are coming out readily. See http://contribs.org
