not really. it was related to the problems with /tmp directories in linux. consider a standard unix-style mailbox. if you make the file append-only, but world writable (not world-readable), anyone can append a message to your mailbox, but only you can rewrite it or read it. the thought is that it would be nice to have a similar capablity with a directory, where the permission to remove is seperated from the permission to create. - erik
