How unique is unique?

Mounting evidence is suggesting that file names, link names and folder names must be unique (Vista 4.1.1), not only within a particular course section, but unique on the server. I’m rubbing my eyes thinking this is insanity … How many faculty will attempt to post a file named syllabus.doc ?

Only this summer’s experience will put this one to bed. Unless someone out there reading this will post an answer as a comment?
