Well okay. I'll admit that I'm a bit windows corrupted ;-)
(As soon as someone begins to talk about system-wide settings, my first 
reaction is that they are talking about the /windows/ registry. Perhaps I'm 
a bit paranoid... :)

But the problem is still there (but considerably less dangerous) if you use 
the word "System-wide" in this way:
Foo.app saves settings in a common file (not in a system dir, just in a 
shared locaton somewhere). Now John Doe's settings will conflict with mine, 
when I run the same app.
(This might be completely harmless, but it might allso lead to quite nasty 
things, depending on how smart the programmer that made the app was :)
(Application settings is system wide, allthough they doesn't actually has 
something with the system to do.)
Actually, I missunderstood the term "System-wide" that Jochem 
Huhmann<joh@unidui.uni-duisburg.de> used, to be of this kind.

(Or, perhaps I didn't. But when I re-reads his letter, I get this creepy 
feeling of having missunderstood something important :-/
