Good enough. (too much o.s. theory I guess) My inital point was simply that at no point do you have a "file that contains other files." After several e-mail exchanges I have altered this to "At no time do you have a File which contains other Files within a single frame of refrence." e.g. you either open all of it with open() or you mount it and open parts with open() but you dont ever open it with open() and then open it's parts with open() based soley on what you retreived from that open, without invoking some File-System-Switch-or-whatever change of context. -- A necessary, but usually moot, distinction.

My thinking is not convoluted; it simply tends to vary between multi-polar states whose description, in terms of spacial relativity, would produce a plane-segment-tiled model of a landscape which may, or may not be, Flat (in some areas ;-)."
