Network filesystem topics

I'm not sure which you're claiming as the disaster.

I would claim that anything other than raw bytes is the disaster. Especially after my experience with OSX and HFS where I once had to completely reformat a laptop to remove a few files after Apple decided to change their Unicode normalization rules.

There was simply no way to get to the old filenames and no way to access the files.

Let the GUI deal with case sensitivity if it must. Let the OS API access a file by an unambiguous stream of bytes terminated by a null.
