what "real" thing? from the perspective of a user program, neglecting #, every file access is through the namespace. each file server has a unique path name, called the qid (as charles mentioned). but between (instances of) file servers, qids are not unique. in general, the problem i think is hard. but fortunately most reasonable questions of unique files can be answered straightforwardly. - erik
