I can see rejecting .. to disallow access above the tree, but rejecting / doesn't make any sense to me. So we have to just plop everything down in one directory? If so, that's ridiculous. I think I need to be less critical of the forkers.
Within Anarki all the file serving was done out of the special docroot directory (at least it was a month ago). I'm not sure if disallowing "../" is what we want or if it what we really want is to ensure that all file serving comes from that dir.
