Calvin Gaisford works on iFolder at Novell, and explained iFolder and how the Open Source project and the Novell product differ. I must admit, at first I was a bit concerned about the workgroup solution (as the Open Source project is called) being a bit crippled, but it seems it should do everything I'm likely to want to use it for. The enterprise solution (the Novell product) differentiates by bringing backup solutions, policies, directory services, support, and so forth.
