Just to add my 2p's worth.

In general I like it.

Lovely ASCII art work :)
but it does have have the n*m problem of such hierarchies.
N types of file:
file, directory, mount-point, drive, root, etc, etc
and M implementations
Posix, NT, linux, OSX, network, database, etc, etc

I would prefer duck-typing.
Add ABCs for all the N types of file and use concrete classes for the 
actual filesystems
That way there are N+M rather than N*M classes.

Although I'm generally against operator overloading, would the // 
operator be better than  the // operator as it is more rarely used and 
more visually distinctive?
