      Btw, version control for ordinary files would be a great feature. I
      think something like it is available through Windows 2000/3 server.
      Isn't it called "Shadow Copies". It works over network shares. :)

      It allows you to restore previous versions of the file even if you
      delete or overwrite it.

      Features like this do make a good point and helps protecting data -
      something that is important IMHO.
